INA129U Description

Short technical summary and product information.

The Texas Instruments INA129U is a precision, low-power instrumentation amplifier designed for general-purpose applications. It features a single channel and supports a wide supply voltage range from ±2.25V to ±18V, with a maximum rating of ±36V.

 

Key electrical specifications include a low input offset voltage of 50µV maximum, a low input offset voltage drift of 0.5µV/°C maximum, and a low input bias current of 5nA maximum. The amplifier provides a high Common Mode Rejection Ratio (CMRR) of 120dB minimum. Its bandwidth at minimum gain (G=1) is 1.3MHz typical, with a maximum gain error of 0.5% and a gain nonlinearity of 0.002% maximum. The noise performance is rated at 8nV/√Hz at 1kHz typical and 0.2µVpp from 0.1Hz to 10Hz typical.

 

The INA129U operates over a wide temperature range of -40°C to 125°C. It is available in 8-pin PDIP and SOIC packages. The device also features overvoltage protection and a low quiescent current of 700µA typical.
