The PGA204BU is a general-purpose Programmable-gain Instrumentation Amplifier offers excellent accuracy. Gains are digitally selected: PGA204-1, 10, 100, 1000V/V. The precision and versatility and low cost of the PGA204 make them ideal for a wide range of applications. Gain is selected by two TTL or CMOS-compatible address lines, A0 and A1. Internal input protection can withstand up to ±40V on the analogue inputs without damage. The PGA204 laser trimmed for very low offset voltage (50μV), drift (0.25μV/°C) and high common-mode rejection (115dB at G=1000). They operate with power supplies as low as ±4.5V, allowing use in battery operated systems. Quiescent current is 5mA.
