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.
