Product Summary

The LT3469ETS8 is a Piezo Microactuator Driver with Boost Regulator. It can can drive outputs up to 33V from a 5V or 12V supply. An internal switching regulator generates a boosted supply voltage for the gm amplifier. The LT3469ETS8 can drive capacitive loads in the range of 5nF to 300nF. Slew rate is limited only by the maximum output current. The 35V output voltage capability of the switching regulator, along with the high supply voltage of the amplifier, combine to allow the wide output voltage range needed to drive a piezoceramic microactuator. The applications of the LT3469ETS8 include Piezo Speakers, Piezo Microactuators, Varactor Bias.
