В® PGA204
PGA205 Programmable Gain
INSTRUMENTATION AMPLIFIER
FEATURES DESCRIPTION в—Џ DIGITALLY PROGRAMMABLE GAIN: 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. PGA204: G=1, 10, 100, 1000V/V
PGA205: G=1, 2, 4, 8V/V
в—Џ LOW OFFSET VOLTAGE: 50ВµV max
в—Џ LOW OFFSET VOLTAGE DRIFT: 0.25ВµV/В°C
в—Џ LOW INPUT BIAS CURRENT: 2nA max Gain is selected by two TTL or CMOS-compatible
address lines, A0 and A1. Internal input protection can
withstand up to В±40V on the analog inputs without
damage. в—Џ LOW QUIESCENT CURRENT: 5.2mA typ
в—Џ NO LOGIC SUPPLY REQUIRED
в—Џ 16-PIN PLASTIC DIP, SOL-16 PACKAGES The PGA204 and PGA205 are laser trimmed for very
low offset voltage (50ВµV), drift (0.25ВµV/В°C) and high
common-mode rejection (115dB at G=1000). They operate with power supplies as low as В±4.5V, allowing use
in battery operated systems. Quiescent current is 5mA. APPLICATIONS
