Video/Imaging Design Line: Supertex designs HV895 inductorless Varioptic liquid lens driver IC and its derivative follow-on ICs.
Supertex claimed its HV895 integrates a charge pump boost converter to drive lenses of up to 200pF with a 1.5kHz waveform at amplitudes up to 60VRMS. The lens driver circuit is contained in a single flip chip die and can be encapsulated within the camera module, the company added.
