Overview
® PGA204 PGA205 Programmable Gain INSTRUMENTATION AMPLIFIER FEATURES q DIGITALLY PROGRAMMABLE GAIN: PGA204: G=1, 10, 100, 1000V/V PGA205: G=1, 2, 4, 8V/V q LOW OFFSET VOLTAGE: 50µV max q LOW OFFSET VOLTAGE DRIFT: 0.
25µV/°C q LOW INPUT BIAS CURRENT: 2nA max q LOW QUIESCENT CURRENT: 5.
2mA typ q NO LOGIC SUPPLY REQUIRED q 16-PIN PLASTIC DIP, SOL-16 PACKAGES DESCRIPTION The PGA204 and PGA205 are low cost, general purpose programmable-gain instrumentation amplifiers offering excellent accuracy.
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 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 (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.
The PGA204 and PGA205 are available in 16-pin plastic DIP, and SOL-16 surface-mount packages, specified for the –40°C to +85°C temperature range.
