The LTC2372-18 is a low noise, high speed, 8-channel 18-bit successive approximation register (SAR) ADC. Operating from a single 5V supply, the LTC2372-18 has a highly configurable, low crosstalk 8-channel input multiplexer, supporting fully differential, pseudo-differential unipolar and pseudo-differential bipolar analog input ranges. The LTC2372-18 achieves ?2.75LSB INL (maximum) in all input ranges, no missing codes at 18-bits and 100dB (fully differential)/ 95dB (pseudo-differential) SNR (typical).The LTC2372-18 has an onboard low drift (20ppm/?C max) 2.048V temperature-compensated reference and a single-shot capable reference buffer. The LTC2372-18 also has a high speed SPI-compatible serial interface that supports 1.8V, 2.5V, 3.3V and 5V logic through which a sequencer with a depth of 16 may be programmed. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2372-18 dissipates only 27mW and automatically naps between conversions, leading to reduced power dissipation that scales with the sampling rate. A sleep mode is also provided to reduce the power consumption of the LTC2372-18 to 300?W for further power savings during inactive periods.Applications Programmable Logic Controllers Industrial Process Control High Speed Data Acquisition Portable or Compact Instrumentation ATE

The ADAL6110-16 is a light detection and ranging (LIDAR)signal processor IC that supports simultaneous capture of up to16 channels. Each channel is integrated with a 16-bit analog todigital converter (ADC) to measure the optical return signal.The ADAL6110-16 stores the captured waveforms to staticrandom access memory (SRAM) storage. The data outputreadout and functional configuration of the LIDAR signalprocessor occurs over a 4-wire serial port interface (SPI).The LIDAR signal processor features a dc balance control toreject signal offset and corruption due to modulated interference,eliminating the need for external dc cancellation circuitry. Inaddition, the LIDAR signal processor has a built-in automaticgain control (AGC) that modifies the gain of the system toensure the signal of interest is automatically scaled to themeasurement range.The ADAL6110-16 simplifies the traditional multichannelLIDAR system implementation by integrating the transimpedanceamplifier (TIA), gain and sampling stages, as well as providingthe transmitter fire signal, all of which are managed by on-chipcontrol logic. No external components are required between thephotodiodes and the TIA interface of each channel in theLIDAR signal processor.Applications Autonomous systems collision avoidance Corridor mapping Dynamic suspension and flight control Drone altitude monitoring Industrial distance measurement Mounted safety curtain systems Parking spot monitoring Blind spot detection

Demonstration circuit 2879A is a high efficiency, high power density hybrid converter. It can deliver 12V/25A with an input voltage from 36V to 60V (up to 65V during transients). This demo board features the LTM4660, which uses an architecture that merges soft-switching switched capacitor topology with a traditional step-down converter to provide superior efficiency compared to the traditional switching architectures. It offers a high efficiency/high density and cost effective solution for nonisolated intermediate bus applications in power distribution, datacom and telecom. Due to its current mode control architecture, multiple LTM4660s can be operated in a parallel, multiphase configuration with excellent current sharing and low output voltage ripple to enable much higher power applications. Other benefits include low EMI emissions due to a soft-switched front end and reduced MOSFET stress. The LTM4660 design eliminates the inrush current typically associated with switched capacitor circuits by pre-balancing the capacitors on start-up. The LTM4660 also monitors system voltage, current and temperature for faults. It stops switching and pulls the FAULT pin low when a fault condition occurs. An onboard timer can be set for appropriate restart/retry times. Additional features include ±1.5% output voltage accuracy over temperature, a clock output for multiphase operation, a power good output signal, short-circuit protection, monotonic output voltage start-up, optional external reference, undervoltage lockout and internal charge balance circuitry. The LTM4660 data sheet must be used in conjunction with this demo board manual.
