PGA300ARHHT

Sensor And Detector Interfaces Overview

The PGA300ARHHT is a sensor signal conditioner and transmitter manufactured by Texas Instruments, designed for resistive bridge sensors. It integrates a programmable gain instrumentation amplifier, a precision voltage reference, and an analog-to-digital converter within a VQFN-36 package. The device operates on a supply voltage ranging from 3.3 V to 30 V with a maximum operating current of 2.5 mA. It supports a wide temperature range from -40°C to +150°C and features a 1-Wire interface for digital communication. Input bias current is specified at 5 nA.
