PS021FN

Sensor And Detector Interfaces Overview

The PS021FN is a strain gauge signal conditioning integrated circuit manufactured by ams OSRAM AG. It utilizes a TDC (Time-to-Digital Converter) architecture to process inputs from resistive sensors. The device operates within a temperature range of -40°C to +120°C and draws a supply current of 150µA. It is housed in a 48-VFQFN package with exposed pad, measuring 7x7 mm. The component is designed for high-precision applications requiring direct digital output from analog sensor signals.
