Programmable gain amplifier PGA for Industrial process control and low power sensors

Overview

The high-performance PGA is highly integrable with our 24b ADC IP and hence can be combined to form a programmable gain Analog front end for precision application. The high-performance PGA can be programmed to have a gain of 1, 2, 4, 8, 16, 32, 64, or 128. The PGA consists of two stages. For a gain of 1, both stages are bypassed. For gains of 2 to 8, a single stage is used, whereas for gains greater than 8, both stages are used. The analog input range is ±VREF/gain
