The Texas Instruments INA321E/2K5 is a single-supply, CMOS instrumentation amplifier designed for cost-optimized applications. It features micropower consumption of only 40µA typical and a shutdown mode that reduces current to less than 1µA.
Key electrical specifications include a low input offset voltage of ±500µV maximum, a wide voltage gain range from 5V/V to 1000V/V, and a high Common-Mode Rejection Ratio (CMRR) of 90dB minimum. The amplifier operates over a supply voltage range of 2.5V to 5.5V and offers a bandwidth of 0.5MHz at minimum gain.
Designed for versatility, the INA321E/2K5 is suitable for various applications such as industrial sensor amplifiers (Bridge, RTD, Thermistor, Position), physiological amplifiers (ECG, EEG, EMG), and A/D converter signal conditioning. Its rail-to-rail output swing and wide operating temperature range of -55°C to 125°C make it robust for demanding environments.
The device is available in a VSSOP (DGK) 8-pin package, measuring 3 mm x 4.9 mm with an area of 14.7 mm². This surface-mount package is suitable for space-constrained designs.
