The AD7124-8 is a low power, low noise, completely integratedanalog front end for high precision measurement applications.The device contains a low noise, 24-bit ?-? analog-to-digitalconverter (ADC), and can be configured to have 8 differentialinputs or 15 single-ended or pseudo differential inputs. The onchiplow gain stage ensures that signals of small amplitude canbe interfaced directly to the ADC.One of the major advantages of the AD7124-8 is that it gives theuser the flexibility to employ one of three integrated powermodes. The current consumption, range of output data rates,and rms noise can be tailored with the power mode selected.The device also offers a multitude of filter options, ensuring thatthe user has the highest degree of flexibility.The AD7124-8 can achieve simultaneous 50 Hz and 60 Hzrejection when operating at an output data rate of 25 SPS (singlecycle settling), with rejection in excess of 80 dB achieved at loweroutput data rates.The AD7124-8 establishes the highest degree of signal chainintegration. The device contains a precision, low noise, lowdrift internal band gap reference and accepts an externaldifferential reference, which can be internally buffered. Otherkey integrated features include programmable low drift excitationcurrent sources, burnout currents, and a bias voltage generator,which sets the common-mode voltage of a channel to AVDD/2.The low-side power switch enables the user to power downbridge sensors between conversions, ensuring the absoluteminimal power consumption of the system. The device alsoallows the user the option of operating with either an internalclock or an external clock.The integrated channel sequencer allows several channels to beenabled simultaneously, and the AD7124-8 sequentially convertson each enabled channel, simplifying communication with thedevice. As many as 16 channels can be enabled at any time, achannel being defined as an analog input or a diagnostic suchas a power supply check or a reference check. This uniquefeature allows diagnostics to be interleaved with conversions.The AD7124-8 also supports per channel configuration. Thedevice allows eight configurations or setups. Each configurationconsists of gain, filter type, output data rate, buffering, andreference source. The user can assign any of these setups on achannel by channel basis.The AD7124-8 also has extensive diagnostic functionalityintegrated as part of its comprehensive feature set. Thesediagnostics include a cyclic redundancy check (CRC), signalchain checks, and serial interface checks, which lead to a morerobust solution. These diagnostics reduce the need for externalcomponents to implement diagnostics, resulting in reducedboard space needs, reduced design cycle times, and cost savings.The failure modes effects and diagnostic analysis (FMEDA) of atypical application has shown a safe failure fraction (SFF) greaterthan 90% according to IEC 61508.The device operates with a single analog power supply from 2.7 Vto 3.6 V or a dual 1.8 V power supply. The digital supply has arange of 1.65 V to 3.6 V. It is specified for a temperature rangeof ?40?C to +125?C. The AD7124-8 is housed in a 32-leadLFCSP package.Note that, throughout this data sheet, multifunction pins, suchas DOUT/RDY, are referred to either by the entire pin name orby a single function of the pin, for example, RDY, when onlythat function is relevant.Applications Temperature measurement Pressure measurement Industrial process control Instrumentation Smart transmitters

The ADM3055E/ADM3057E are 5 kV rms and 3 kV rms isolated controller area network (CAN) physical layer transceivers with integrated isolated dc-to-dc converters. The ADM3055E/ADM3057E meet flexible data rate (CAN FD) requirements for operation to 5 Mbps and higher and comply with the ISO 11898-2: 2016 standard. The ADM3055E/ADM3057E are capable of supporting data rates as high as 12 Mbps.The devices employ Analog Devices, Inc., iCoupler? technology to combine a 3-channel isolator, a CAN transceiver, and an Analog Devices isoPower? dc-to-dc converter into a single, surface-mount, small outline integrated circuit (SOIC) package. The devices are powered by a single 5 V supply, realizing a fully isolated solution for CAN and CAN FD. Radiated emissions from the high frequency switching of the dc-to-dc convertors are kept below EN 55022 Class B limits by continuous adjustments to the switching frequency.The ADM3055E/ADM3057E provide complete isolation between the CAN controller and physical layer bus. Safety and regulatory approvals (pending) for 5 kV rms isolation voltage, 10 kV surge test, and 8.3 mm creepage and clearance ensure the ADM3055E meets application reinforced isolation requirements. The ADM3057E has an isolation voltage of 3 kV rms and 7.8 mm creepage in a 20-lead, wide body SOIC.Low propagation delays through the isolation support longer bus cables. Slope control mode is available for standard CAN at low data rates. Standby mode minimizes power consumption when the bus is idle or if the node goes offline. Silent mode allows the TXD input to be ignored for listen only mode.Dominant timeout functionality protects against bus lock up in a fault condition. The current limiting and thermal shutdown features protect against output short circuits. The devices are fully specified over an industrial temperature range of ?40?C to +105?C.Applications CANOpen, DeviceNet, and other CAN bus implementations Industrial automation Process control and building control Transport and infrastructure

The ADF5610 allows implementation of fractional-N or Integer N phase-locked loop (PLL) frequency synthesizers when used with an external loop filter and an external reference source. The wideband microwave voltage controlled oscillator (VCO) design permits frequency operation from 7300 MHz to 14600 MHz at a single radio frequency (RF) output. A series of frequency dividers with a differential frequency output allows operation from 57 MHz to 14600 MHz. Analog and digital power supplies for the PLL circuitry range from 3.1 V to 3.5 V, and the VCO supplies are between 4.75 V and 5.25 V. The charge pump supply voltage can be extended up to 3.6 V for improved frequency band overlap and extended upper frequency range.The ADF5610 has an integrated VCO with a fundamental frequency of 3650 MHz to 7300 MHz. These frequencies are internally doubled and routed to the RFOUT pin. An additional differential output allows the doubled VCO frequency to be divided by 1, 2, 4, 8, 16, 32, 64, or 128, allowing the user to generate RF output frequencies as low as 57 MHz. A simple 3?wire serial port interface (SPI) provides control of all on-chip registers. To conserve power, this divider block can be disabled when not needed through the SPI interface. Likewise, the output power for both the single-ended output and the differential output are programmable via the VCO register settings. The ADF5610 also contains various power-down modes for the VCO circuitry and PLL circuitry.The integrated phase detector (PD) and delta-sigma (?-?) modulator, capable of operating at up to 100 MHz, permit wide loop bandwidths and fast frequency tuning with a typical spurious level of ?100 dBc.With phase noise levels from ?115 dBc/Hz at 7.3 GHz to ?109 dBc/Hz at 14.6 GHz, the ADF5610 is equipped to minimize blocker effects, and to improve receiver sensitivity and transmitter spectral purity. The low phase noise floor eliminates any contribution to modulator and mixer noise floor in transmitter applications.The ADF5610 is a PLL with integrated VCO. The device features an innovative programmable performance technology that enables the ADF5610 to tailor current consumption and corresponding noise performance to individual applications by selecting either a low current consumption mode or a high performance mode for improved phase noise performance.Additional features of the ADF5610 include approximately 3 dBof RFOUT gain control in 1.5 dB steps and 5 dB of control onthe differential port in approximately 2.5 dB steps. Finally, the ?-?modulator with exact frequency mode enables users to generateoutput frequencies with 0 Hz frequency error.APPLICATIONSMilitary and defenseTest equipmentClock generationWireless infrastructureSatellite and very small aperture terminal (VSAT)Microwave radio
