The Texas Instruments INA129P 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 4.5V to 36V.
Key electrical specifications include a minimum voltage gain of 1 and a maximum of 10000, with a bandwidth of 1.3MHz at minimum gain. The device boasts a low input offset voltage of 50µV maximum and a low input offset drift of 0.5µV/°C maximum. Noise performance is excellent, with 8nV/√Hz at 1kHz and 0.2µVpp from 0.1Hz to 10Hz. It also provides high Common Mode Rejection Ratio (CMRR) of 120dB minimum.
Additional features include current feedback, overvoltage protection, and a low quiescent current of 0.7mA typical. The input is protected to ±40V. The INA129P is available in 8-pin PDIP and 8-pin SOIC packages, suitable for operation across a wide temperature range of -40°C to 125°C.
