概述

The TPAFE51760 is a 16-channel, 16-bit, dual simultaneous 2 x 1 MSPS sampling system based on successive approximation register (SAR) analog-to-digital converter (ADC). The TPAFE51760 is highly integrated with an analog front-end for each channel, including an input overvoltage clamp, 1 MΩ input impedance, programmable gain amplifier (PGA), active low-pass filter, and ADC driver. Internal precision and low-drift reference with buffer make the device feasible for compact data acquisition solutions. The digital interface supports communication with various host controllers with SPIcompatible serial and parallel interfaces.

The TPAFE51760 can process true bipolar ± 10 V, ±5 V, and ±2.5 V input signals, with a single 5 V analog power supply. The 1 MΩ high input impedance simplified analog input design and the device can be connected directly with sensors. The analog input overvoltage could protect the device up to ±30 V. The device offers a flexible sequencer that allows it to be configured and burst mode is also supported. On-chip oversampling digital filters can be used to improve SNR and reduce throughput rates. Integrated chip self-detect function and optional CRC make the device robust in the application.

The TPAFE51760 is available in the LQFP14x14-80 package and operates from −40°C to +125°C.
