概述

The TPAFE51716H is a single-channel, 16-bit, 1 MSPS sampling system based on a successive approximation register (SAR) analog-to-digital converter (ADC). The TPAFE51716H is highly integrated with analog front-end for each channel, including 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 makes the device feasible for a compact data acquisition solution. The digital interface supports communication with various host controllers with SPI-compatible serial and daisy-chaining of multiple devices.

The TPAFE51716H can process true bipolar single-ended ±12.288 V, ±10.24 V, ±6.144 V, ±5.12 V, ±3.072 V, ±2.56 V, unipolar single-ended 0 V - 12.288 V, 0 V - 10.24 V, 0 V - 6.144 V, 0 V - 5.12 V, and true bipolar fully-differential ±12.288 V, ±10.24 V, ±6.144 V, ±5.12 Vinput 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 to sensors. The analog input overvoltage could protect the device up to ±30 V. The device offers a simple SPI-compatible serial interface and also supports daisy-chaining of multiple devices.

The device integrates various diagnostic functions to improve system robustness, like analog input open detection, alarm, and CRC error checking on read and write data and registers.

The TPAFE51716H is available in the TSSOP 5x4.4-16 package and operates from −40°C to +125°C.
