INA188IDR Description

Short technical summary and product information.

The Texas Instruments INA188IDR 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 a low input offset drift of 0.2 µV/°C maximum. 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.

 

The gain is set with a single external resistor, offering flexibility in configuration. The device supports rail-to-rail output swing and has input common-mode headroom specifications. It is available in SOIC and WSON packages, suitable for various board space constraints.

 

With its zero-drift architecture and robust performance, the INA188IDR is well-suited for applications requiring accurate signal amplification in demanding environments.
