3 Description

The INA128-HT and INA129-HT 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 10000.

The INA128-HT provides an industry-standard gain

equation; the INA129-HT gain equation is compatible

with the AD620.

The INA128-HT and INA129-HT are laser trimmed for

very low offset voltage (25 μV Typ) and high

common-mode rejection (93 dB at G ≥ 100). These devices operate 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.

Texas Instruments' high-temperature products use

highly optimized silicon (die) solutions with design

and process enhancements to maximize performance

over extended temperatures.

The INA129-HT 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-

HT is available in an 8-pin SOIC-8 surface-mount

package, specified for the –55°C to 175°C temperature range.
