Product Introduction

Overview

The PGA205AUG4, produced by Texas Instruments, is a low-cost, general-purpose programmable-gain instrumentation amplifier. It offers excellent accuracy and versatility, making it ideal for a wide range of applications. The PGA205 is part of the PGA204 and PGA205 series, which are known for their precision and low cost. Gains are digitally selected using two TTL or CMOS-compatible address lines, A0 and A1, allowing for gains of 1, 2, 4, and 8 V/V. The device is available in 16-pin plastic DIP and SOL-16 surface-mount packages and operates over a temperature range of -40°C to 85°C.
