The Texas Instruments INA121U is a FET-input, low power instrumentation amplifier designed for high accuracy applications. It operates over a wide supply voltage range from ±4.5V to ±18V, with a typical quiescent current of 0.45mA.
Key electrical specifications include a low input offset voltage of ±500µV maximum, a low input bias current of ±0.05nA maximum, and a high Common-Mode Rejection Ratio (CMRR) of 106dB minimum. The amplifier offers a voltage gain range from 1 to 10000 V/V and a bandwidth of 0.6MHz at minimum gain.
For enhanced reliability, the INA121U includes overvoltage protection up to ±40V. It is available in SOIC and PDIP packages, suitable for various mounting requirements.
This instrumentation amplifier is well-suited for applications requiring precise signal conditioning and amplification due to its combination of low noise, low offset, and high CMRR.
