INA331IDGKT

The INA331IDGKT is a low-power single supply CMOS Instrumentation Amplifier with rail-to-rail output. It offers wide range, single-supply operation as well as bipolar-supply operation. The INA331 family provides low-noise amplification of differential signals with a low quiescent current of 415µA (dropping to 0.01µA 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 INA331 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.
