General Description

The INA188 is a precision instrumentation amplifier that uses TI 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.
