Overview

The TPAFE51736S8 is an 8-channel, 16-bit, 500 kSPS sampling system based on a successive approximation register (SAR) analog-to-digital converter (ADC). The TPAFE51736S8 is highly integrated with an analog frontend 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 a compact data acquisition solution. The digital interface supports communication with various host controllers with SPI-compatible serial and daisychaining of multiple devices.

The TPAFE51736S8 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 V input signals, with 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 can 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 and CRC error checking on read and write data and registers.

The TPAFE51736S8 is available in the 38-lead TSSOP 9.7 mm x 4.4 mm package and operates from −40°C to +125°C.
