INA2128

SBOS035A – DECEMBER 1995 – REVISED APRIL 2007

Dual, Low Power

INSTRUMENTATION AMPLIFIER

DESCRIPTION

FEATURES

TheINA2128isadual, lowpower, generalpurposeinstrumen-

tation amplifier offering excellent accuracy. Its versatile

3-op amp design and small size make it ideal for a wide range

of applications. Current-feedback input circuitry provides wide

bandwidth even at high gain (200kHz at G = 100).

ꢀ LOW OFFSET VOLTAGE: 50µV max

ꢀ LOW DRIFT: 0.5µV/°C max

ꢀ LOW INPUT BIAS CURRENT: 5nA max

ꢀ HIGH CMR: 120dB min

ꢀ INPUTS PROTECTED TO ±40V

ꢀ WIDE SUPPLY RANGE: ±2.25V to ±18V

ꢀ LOW QUIESCENT CURRENT: 700µA / IA

ꢀ 16-PIN PLASTIC DIP, SOL-16

A single external resistor sets any gain from 1 to 10,000.

Internal input protection can withstand up to ±40V without

damage.

The INA2128 is laser-trimmed for very low offset voltage

(50µV), drift (0.5µV/°C) and high common-mode rejection

(120dB at G ≥ 100). It operates with power supplies as low as

±2.25V, and quiescent current is only 700µA per IA—ideal for

battery-operated and multiple-channel systems.

APPLICATIONS

ꢀ SENSOR AMPLIFIER

THERMOCOUPLE, RTD, BRIDGE

The INA2128 is available in SOL-16 packages, specified

for the –40°C to +85°C temperature range.
