HV895 Description
The HV895 is designed to drive liquid lenses of up to 200pF with a 1.5kHz waveform at amplitudes up to 60VRMS, controlled via an I2C interface. A single byte (AMP) written to the HV895 controls the operation of the driver. Setting AMP = 01h to FFh controls output amplitude in 255 monotonic steps.
