描述 Description

TPAFE5160 is a 16bit, 8-channel simultaneous

sampling, successive approximation (SAR) ADC.

Each channel has a complete analog front end, as

well as an ADC operating at 350 kSPS per channel.

The analog front end features input clamp, a

programmable gain amplifier (PGA) with high input

impedance of 1MΩ， low pass filter and ADC input

driver.

The device features an internal precision reference

with buffer to driver the ADC. A digital interface

supports serial, parallel and parallel byte

communication, which can be used with varies host

controllers.

The TPAFE5160 can accept ±10V or ± 5V true bipolar

inputs with a single 5V supply. Also the high input

impedance allows direct connection to transformers

or other sensors without external driver circuits.

The zero latency conversion with high performance

also makes the device suitable for industrial

automation and control applications.
