HV892 Datasheet (Supertex) - Inductorless Liquid Lens Driver

HV892, Inductorless Liquid Lens Driver

The HV892 liquid lens driver is controlled via an I2C interface, is capable of driving capacitive loads of up to 200pF, and is compatible with 40VRMS to 60VRMS lenses.

A single byte (AMP) written to the HV892 controls the operation of the driver.

Setting AMP = 01h to FFh controls output amplitude in
