DESCRIPTION

The INA128 and INA129 are low power, general purpose instrumentation amplifiers offering excellent accuracy.

The versatile three operational amplifier design and small size make them ideal for a wide range of applications.

Current-feedback input circuitry provides wide bandwidth even at high gain.

A single external resistor sets any gain from 1 to 10,000. The INA128 provides an industry-standard gain

equation; the INA129 gain equation is compatible with the AD620.

The INA128/INA129 is laser trimmed for very low offset voltage (50

μV) and high common-mode rejection (93 dB

at G

≥ 100). It operates with power supplies as low as ±2.25 V, and quiescent current of 2 mA - typically. Internal

input protection can withstand up to ±40 V without damage.

The INA129 is available in 8-pin ceramic DIP and 8-pin ceramic surface-mount packages, specified for the –55°C

to 210°C temperature range. The INA128 is available in an 8-pin SO-8 surface-mount package, specified for the

–55°C to 175°C temperature range.
