INA122U Description

Short technical summary and product information.

The INA122U from Texas Instruments is a precision instrumentation amplifier engineered for accurate and low-noise differential signal acquisition. Its two-op-amp design delivers excellent performance while maintaining very low quiescent current, making it suitable for portable instrumentation and data acquisition systems.

 

Key electrical specifications include a wide power supply range from 2.2V to 36V, a low input offset voltage of 250µV maximum, and a low input offset drift of 3µV/°C maximum. The amplifier offers a gain range from 5V/V to 10000V/V, with a typical noise level of 60nV/√Hz at 1kHz. It also features a low input bias current of 25nA maximum and a low quiescent current of 60µA typical.

 

The INA122U supports both single and dual power supply operation. It is available in SOIC and PDIP packages. The operating temperature range is -40°C to 85°C.

 

This instrumentation amplifier is ideal for applications requiring precise signal conditioning and amplification, particularly where low power consumption is a critical design factor.
