Gains are digitally selected: PGA204-1, 10, 100, 1000, and PGA205-1, 2, 4, 8V/V. The precision and versatility, and low cost of the PGA204 and PGA205 make them ideal for a wide range of applications.
Gain PGA204 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 PGA204 and PGA205 are laser trimmed for very low offset voltage (50mV), drift (0.25mV/) 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.
The PGA204 and PGA205 are available in 16-pin plastic DIP, and SOL-16 surface-mount packages, specified for the 40 to +85 temperature range.
