PGA205 IC Chip

PGA205 (Programmable Gain Instrumentation Amplifier) 

Introduction

The PGA205 is low cost, general purpose programmable-gain instrumentation amplifiers offering excellent accuracy. Gain is digitally selected: PGA205-1,2, 4, 8V/V. The precision and versatility, and low cost of  the device makes it ideal for a wide range of applications.

Gain is selected by two TTL or CMOS-compatible address lines, Ao and A1.Internal input protection can withstand up to ±40V on the analog inputs without damage.

The PGA205 is laser trimmed for very low offset voltage (50µV), drift (0.25µV/°C) and high common-mode rejection (115dB at G=1000). It operates with power supplies as low as ±4.5V, allowing use in battery operated systems. Quiescent current is 5mA.

The device is available in 16-pin plastic DIP, and SOL-16 surface-mount packages, specified for the -40°C to +85°C temperature range.
