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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
