The ADGM1004 is a wideband, single-pole, four-throw (SP4T)?switch fabricated using Analog Devices, Inc., microelectro-mechanical system (MEMS) switch technology. This technology enables a small form factor, wide RF bandwidth, highly linear, low insertion loss switch that is operational from 0 Hz/dc to 13 GHz, making it an ideal solution for a wide range of RF and precision?equipment switching needs.An integrated driver chip generates a high voltage to electrostatically actuate switch that can be controlled by a parallel interface and a serial peripheral interface (SPI). All four switches are independently controllable.The device is packaged in a 24-lead, 5 mm ? 4 mm ? 1.45 mm, lead frame chip-scale package (LFCSP).To ensure optimum operation of the ADGM1004, follow the?Critical Operational Requirements section exactly. The on resistance (RON) performance of the ADGM1004 is?affected by part to part variation, channel to channel variation,?cycle actuations, settling time post turn on, bias voltage, and?temperature changes. Note that throughout this data sheet, multifunction pins, such?as IN1/SDI, are referred to either by the entire pin name or by a?single function of the pin, for example, SDI, when only that function is relevant.Applications Relay replacements Automatic test equipment (ATE): RF, digital, and mixed signals Load and probe boards: RF, digital, and mixed signals RF test instrumentation Reconfigurable filters and attenuators High performance RF switching

The ADGS1412 contains four independent single-pole/single-throw(SPST) switches. A serial peripheral interface (SPI)controls the switches. The SPI interface has robust error detectionfeatures such as cyclic redundancy check (CRC) error detection,invalid read/write address detection, and SCLK count errordetection.It is possible to daisy-chain multiple ADGS1412 devices together.Daisy-chain mode enables the configuration of multiple deviceswith a minimal amount of digital lines. The ADGS1412 can alsooperate in burst mode to decrease the time between SPIcommands.iCMOS construction ensures ultralow power dissipation, makingthe device ideally suited for portable and battery-poweredinstruments.Each switch conducts equally well in both directions when on,and each switch has an input signal range that extends to thesupplies. In the off condition, signal levels up to the suppliesare blocked.The on-resistance profile is flat over the full analog input range,which ensures good linearity and low distortion when switchingaudio signals.Product Highlights SPI interface removes the need for parallel conversion, logic traces and reduces general-purpose input/output (GPIO) channel count. Daisy-chain mode removes additional logic traces when multiple devices are used. CRC error detection, invalid read/write address detection, and SCLK count error detection ensures a robust digital interface. CRC and error detection capabilities allow the use of the ADGS1412 in safety critical systems. Guaranteed break-before-make switching allows the use of the ADGS1412 in multiplexer configurations with external wiring.

DC1786A: Demo Board for the LTC2871 RS232/RS485 Multiprotocol Transceivers with Integrated Termination.

The LTM2884 is a complete galvanically isolated USB 2.0 compatible ?Module? (micromodule) transceiver. An upstream supply powers both sides of the interface through an integrated, isolated DC/DC converter.The LTM2884 is ideal for isolation in host, hub, bus splitter or peripheral device applications. It is compatible with USB 2.0 full speed (12Mbps) and low speed (1.5Mbps) operation. Automatic speed selection configures integrated pull-up resistors on the upstream port to match those sensed on the downstream device.The isolator ?Module technology uses coupled inductors and an isolated power transformer to provide isolation between the upstream and downstream USB interface. This device is ideal for systems requiring isolated ground returns or large common mode voltage variations. Uninterrupted communication is guaranteed for common mode transients greater than 30kV/?s.Enhanced ESD protection allows this part to withstand up to ?15kV (human body model) on the USB transceiver interface pins to local supplies and ?15kV through the isolation barrier to supplies without latch-up or damage.Applications Isolated USB Interfaces Host, Hub, or Device Isolation Industrial/Medical Data Acquisition

Demonstration circuit 1801A is a dual output 1.5V/20A and 1.2V/20A synchronous buck converter operating with a switching frequency of 300kHz over an input voltage range of 4.5V to 14V. The demo board comes in two versions. The A version uses inductor DCR current sensing for high efficiency. The B version uses 2mΩ sense resistor for accurate current sensing with a low DCR ferrite inductor. The fixed on-time valley current mode topology of the LTC3838 allows for a fast load step response.

The LTC6362 is a low power, low noise differential op amp with rail-to-rail input and output swing that has been optimized to drive low power SAR ADCs. The amplifier may be configured to buffer a fully differential input signal or convert a single-ended input signal to a differential output signal.

Demonstration circuit 1812A (Figure 1) features the LTC2943. The LTC2943 has an operating range of 3.6V to 20V making it perfectly suited for multicell battery applications. A precision analog coulomb counter integrates current measured through a sense resistor between the battery’s positive terminal and the load or charger. The default value assembled on the DC1812A-A is 100mΩ for a maximum current measurement of 500mA. The LTC2943 measures voltage, current and temperature with an internal 14-bit No Latency ΔΣ™ ADC. The measurements are stored in internal registers accessible via the onboard SMBus/I2C interface.
