The INA149AID is a low-power, single-supply precision instrumentation amplifier from Texas Instruments. It is optimized for noise and power, consuming just 270 uA of current, with a noise density of just 0.7 µV/vHz. This device offers a high common-mode rejection ratio (CMRR) of 94 dB, and provides rail-to-rail input and output for output levels within one LSB of the supply rails. The INA149AID also features full-scale output offset of 14 mV, giving ±15 mV output swing when driving full-scale. It is capable of operating over a wide temperature range of –40°C to +145°C.
