Overview
The INA129MDREP is a precision, low-power instrumentation amplifier manufactured by Texas Instruments. It features a single channel with a gain range of 1 V/V to 10,000 V/V and a 3dB bandwidth of 1.3 MHz. Key electrical specifications include a slew rate of 4 V/us, a common-mode rejection ratio (CMRR) of 113 dB, an input bias current of 50 nA, and an input offset voltage of 25 uV. The device operates on supply voltages between 4.5 V and 36 V with a typical operating current of 2 mA. It supports an extended temperature range from -55 C to +210 C and is housed in a CDIP-8 package.
