The Texas Instruments INA188ID is a high-voltage instrumentation amplifier designed for precision measurements. It features a wide supply voltage range, supporting single supplies from 4 V to 36 V and dual supplies from ±2 V to ±18 V.
Key electrical characteristics include a low input offset voltage of 55 µV maximum and an input offset drift of 0.2 µV/°C maximum, ensuring stable performance over temperature. The amplifier provides a high Common-Mode Rejection Ratio (CMRR) of 104 dB at a gain of 10 or higher. Noise performance is also notable, with a low input noise density of 12.5 nV/√Hz at 1 kHz and 0.25 µVPP from 0.1 Hz to 10 Hz.
Gain is set with a single external resistor, offering flexibility with a gain range from 1 to 1000. The device features RFI-filtered inputs and a rail-to-rail output, maximizing dynamic range. It operates across a wide temperature range of -55°C to +150°C.
The INA188ID is available in SOIC-8 and WSON-8 packages, with the WSON-8 offering a smaller footprint of 16 mm² compared to the SOIC-8's 29.4 mm².
