CJMCU-29 INA129HT High Precision Low Power Instrumentation Amplifier

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.
