TPAFE516 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 TPAFE516 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.
