Abstract:
An integrated circuit to drive a plurality of fluid actuation devices includes a strain gauge sensor, an amplifier, and a voltage bias generator. The strain gauge sensor generates a strain gauge signal. The amplifier amplifies the strain gauge signal. The voltage bias generator offsets the amplified strain gauge signal.
