Using a special manufacturing flow, the INA332 family provides the lowest cost available, while still achieving low-noise amplification of differential signals with low quiescent current of 415µA (dropping to 0.01µA when shut down). Returning to normal operation within microseconds, this INA can be used for battery or multichannel applications. Configured internally in a gain of 5V/V, the INA332 offers flexibility in higher gains by choosing external ...
