PGA204 description

PGA204 and PGA205 are low-cost, general-purpose programmable gain Instrumentation amplifier with excellent accuracy. The gain is selected in digital mode: PGA204-1,10,100,1000 and PGA205-1,2,4,8V/V. The precision, versatility and low cost of PGA204 and PGA205 make them ideal for wide applications.

GAIN is selected by two TTL or CMOS compatible address lines a 0 and a 1. Internal input protection can withstand up to ± 40V of voltage on analog inputs without damage.

PGA204 and PGA205 can achieve extremely low offset voltage (50μv) , drift (0.25 μv/° C) and high common-mode suppression (115dB at G = 1000) . They are powered by a power supply as low as ± 4.5 V and allow use in battery-powered systems. The static current is 5 Ma.
