DESCRIPTION

The INA128 and INA129 are low power, general

purpose instrumentation amplifiers offering excellent

accuracy. Their versatile 3-op amp design and small

size make them ideal for a wide range of applications.

Current-feedback input circuitry provides wide band-

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

A single external resistor sets any gain from 1 to

10,000. INA128 provides an industry standard gain

equation; INA129’s gain equation is compatible with

the AD620.

The INA128/INA129 is laser trimmed for very low

offset voltage (50µV), drift (0.5µV/°C) and high com-

mon-mode rejection (120dB at G

≥

100). It operates

with power supplies as low as

±2.25V,

and quiescent

current is only 700µA—ideal for battery operated

systems. Internal input protection can withstand up to

±40V

without damage.

The INA128/INA129 is available in 8-pin plastic

DIP, and SO-8 surface-mount packages, specified for

the –40°C to +85°C temperature range. The INA128

is also available in dual configuration, the INA2128.
