PGA900AYZSR

Sensor And Detector Interfaces Overview

The PGA900AYZSR is a programmable resistive sensing conditioner manufactured by Texas Instruments. It integrates a high-precision instrumentation amplifier, a 16-bit sigma-delta analog-to-digital converter (ADC), and a digital signal processor to interface directly with resistive bridge sensors. The device supports an operating supply voltage range from 3.0 V to 5.5 V and draws a typical supply current of 4.2 mA. It features a wide common-mode rejection ratio (CMRR) of 110 dB at 60 Hz and operates within a temperature range of -40°C to +125°C. The component is housed in a 48-pin QFN package.
