The PGA205BU is a general purpose programmable-gain Instrumentation Amplifier offering excellent accuracy. Digitally controlled gain of 1, 2, 4 and 8V/V. Gain is selected by two TTL or CMOS-compatible address lines, A0 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 operate with power supplies as low as ±4.5V, allowing use in battery operated systems.
