DC1699A-A: Demo Board for the LT6108 High Side Current Sense Amplifier with Reference and Comparator.

The LTC2995 is a high accuracy temperature sensor and dual supply monitor. It converts the temperature of an external diode sensor and/or its own die temperature to an analog output voltage while rejecting errors due to noise and series resistance. Two supply voltages and the measured temperature are compared against upper and lower limits set with resistive dividers. If a threshold is exceeded, the device communicates an alert by pulling low the correspondent open drain logic output.The LTC2995 gives ?1?C accurate temperature results using commonly available NPN or PNP transistors or temperature diodes built into modern digital devices. Voltages are monitored with 1.5% accuracy. A 1.8V reference output simplifies threshold programming and can be used as an ADC reference input.The LTC2995 provides an accurate, low power solution for temperature and voltage monitoring in a compact 3mm ? 3mm QFN package.Applications Network Servers Core, I/O Voltage Monitors Desktop and Notebook Computers Environmental Monitoring

The receive path consists of two independent, wide bandwidth (BW), direct conversion receivers with state-of-the-art dynamic range. The complete receive subsystem includes automatic and manual attenuation control, dc offset correction, quadrature error correction (QEC), and digital filtering, eliminating the need for these functions in the digital baseband. RF front-end control and several auxiliary functions such as analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and general-purpose input/outputs (GPIOs) for the power amplifier (PA) are also integrated.In addition to automatic gain control (AGC), the ADRV9008-1 also features flexible external gain control modes, allowing significant flexibility in setting system level gain dynamically.The received signals are digitized with a set of four high dynamic range, continuous time, sigma-delta (?-?) ADCs that provide inherent antialiasing. The combination of the direct conversion architecture, which does not suffer from out of band image mixing, and the lack of aliasing relaxes the requirements of the RF filters compared to traditional intermediate frequency (IF) receivers.The fully integrated phase-locked loop (PLL) provides high per-formance, low power, fractional-N, RF synthesis for the receiver signal paths. An additional synthesizer generates the clocks needed for the converters, digital circuits, and the serial interface. A multi-chip synchronization mechanism synchronizes the phase of the RF local oscillator (LO) and baseband clocks between multiple ADRV9008-1 chips. Precautions are taken to provide the isolation required in high performance base station applications. All voltage controlled oscillators (VCOs) and loop filter components are integrated.The high speed JESD204B interface supports up to 12.288 Gbps lane rates, resulting in two lanes per transmitter and a single lane per receiver in the widest bandwidth mode. The interface also supports interleaved mode for lower bandwidths, reducing the total number of high speed data interface lanes to one. Both fixed and floating point data formats are supported. The floating point format allows internal AGC to be invisible to the demodulator device.The core of the ADRV9008-1 can be powered directly from 1.3 V and 1.8 V regulators and is controlled via a standard 4-wire serial port. Comprehensive power-down modes are included to mini-mize power consumption during normal use. The ADRV9008-1 is packaged in a 12 mm ? 12 mm, 196-ball chip scale ball grid array (CSP_BGA).Applications 3G, 4G, and 5G FDD, macrocell base stations Wide band active antenna systems Massive multiple input, multiple output (MIMO) Phased array radar Electronic warfare Military communications Portable test equipment

Demonstration circuit 1307B features the LTM8027 configured to deliver 12V/4A from a 16V to 60V input. The wide input range of the LTM8027 allows a variety of input sources such as automotive batteries, wall adaptors and industrial supplies. The LTM8027 is a step down converter, so a minimum amount of headroom is required to keep the output in regulation. A soft-start feature controls the output voltage slew rate at start-up, reducing current surges and voltage overshoots.

The ADG1421 / ADG1422?/ ADG1423?contain two independent single-pole/single-throw (SPST) switches. The ADG1421 and ADG1422 differ only in that the digital control logic is inverted. The ADG1421 switches are turned on with Logic 1 on the appropriate control input, and Logic 0 is required for the ADG1422. The ADG1423 has one switch with digital control logic similar to that of the ADG1421; the logic is inverted on the other switch. The ADG1423 exhibits break-before-make switching action for use in multiplexer applications. Each switch conducts equally well in both directions when on and has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked.The iCMOS? (industrial CMOS) modular manufacturing process combines high voltage, complementary metal-oxide semiconductor (CMOS) and bipolar technologies. It enables the development of a wide range of high performance analog ICs capable of 33 V operation in a footprint that no other generation of high voltage parts has achieved. Unlike analog ICs using conventional CMOS processes, iCMOS components can tolerate high supply voltages while providing increased performance, dramatically lower power consumption, and reduced package size.The on resistance profile is very flat over the full analog input range ensuring excellent linearity and low distortion when switching audio signals. The iCMOS construction ensures ultralow power dissipation, making the part ideally suited for portable and battery-powered instruments.PRODUCT HIGHLIGHTS 2.4 ? maximum on resistance at 25?C.

The LTC1474/LTC1475 series are high efficiency step-down converters with internal P-channel MOSFET power switches that draw only 10?A typical DC supply current at no load while maintaining output voltage. The LTC1474 uses logic-controlled shutdown while the LTC1475 features pushbutton on/off.The low supply current coupled with Burst Mode? operation enables the LTC1474/LTC1475 to maintain high efficiency over a wide range of loads. These features, along with their capability of 100% duty cycle for low dropout and wide input supply range, make the LTC1474/LTC1475 ideal for moderate current (up to 300mA) battery-powered applications.The peak switch current is user-programmable with an optional sense resistor (defaults to 325mA minimum if not used) providing a simple means for optimizing the design for lower current applications. The peak current control also provides short-circuit protection and excellent start-up behavior. A low-battery detector that remains functional in shutdown is provided.The LTC1474/LTC1475 series availability in 8-lead MSOP and SO packages and need for few additional components provide for a minimum area solution.Applications Cellular Telephones and Wireless Modems 4mA to 20mA Current Loop Step-Down Converter Portable Instruments Battery-Operated Digital Devices Battery Chargers Inverting Converters Intrinsic Safety Applications
