NOTES: (1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. (2) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.5V beyond the supply rails should be current limited to 10mA or less. (3) Short-circuit to ground, one amplifier per package.




Description

The INA2331 are rail-to-rail output, low-power CMOS instrumentation amplifiers that offer wide range, singlesupply operation as well as bipolar-supply operation. The INA331 family provides low-cost, low-noise amplification of differential signals with a low quiescent current of 415A (dropping to 0.01A when shutdown). Returning to normal operation within microseconds, this INA can be used for  battery or multi-channel applications.

Configured internally in a gain of 5V/V, the INA331 offers flexibility in higher gains by choosing external resistors.

The INA2331 rejects line noise and its harmonics, because common-mode error remains low even at higher frequencies. High bandwidth and slew rate makes the INA331 ideal for directly driving sampling Analog-to-Digital (A/D) converters as well as general-purpose applications.

With high precision, low cost, and small packages, the INA2331 outperforms discrete designs.

Additionally, because they are specified for wide temperature range of 55 to +125 and operating range of 65 to +150, they can be used in demanding industrial and automotive environments.
