The Texas Instruments INA321E is a single-supply, CMOS instrumentation amplifier designed for cost-optimized applications. It features micropower consumption with a typical quiescent current of 40µA and a shutdown mode drawing less than 1µA.
Key electrical specifications include a wide supply voltage range of 2.5V to 5.5V, a low input offset voltage of ±500µV maximum, and a high Common Mode Rejection Ratio (CMRR) of 90dB minimum. The voltage gain can be set externally with resistors, ranging from 5V/V to 1000V/V. It offers a bandwidth of 0.5MHz at minimum gain and a gain error of ±0.1% maximum.
The INA321E provides rail-to-rail output swing and features input common-mode headroom from 0.55V to the negative supply and -1.7V to the positive supply. Its operating temperature range is -55°C to 125°C.
Packaged in a VSSOP (DGK) 8-pin surface mount package with dimensions of 3mm x 4.9mm, this instrumentation amplifier is suitable for applications such as industrial sensor amplifiers, physiological signal conditioning, and A/D converter signal conditioning.
