0mm flip-chip General 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.
Setting AMP = 00h causes the HV895 to go into low powe...
