INA188ID

36V、零漂移、轨到轨输出仪表放大器 8-SOIC -40 to 125

The INA188 is a precision instrumentation amplifier that uses proprietary auto-zeroing techniques to achieve low offset voltage, near-zero offset and gain drift, excellent linearity, and exceptionally low-noise density 12 nV/√Hz that extends down to dc.

The INA188 is optimized to provide excellent common-mode rejection of greater than 104 dB G ≥ 10. Superior common-mode and supply rejection supports high-resolution, precise measurement applications. The versatile three op-amp design offers a rail-to-rail output, low-voltage operation from a 4-V single supply as well as dual supplies up to ±18 V, and a wide, high-impedance input range. These specifications make this device ideal for universal signal measurement and sensor conditioning such as temperature or bridge applications.

A single external resistor sets any gain from 1 to 1000. The INA188 is designed to use an industry-standard gain equation: G = 1 + 50 kΩ / RG. The reference pin can be used for level-shifting in single-supply operation or for an offset calibration.

The INA188 is specified over the temperature range of –40°C to +125°C .
