The HV861K7-G is a low noise, dimmable, high voltage, dual EL Lamp driver designed for driving two electroluminescent (EL) Lamps with a combined area of 5.0 square inches. The input supply voltage range is from 2.5V to 4.5V. Enable input logic high can go as low as 1.5V, which allows logic interface operating from typical 1.8V supplies. The device is designed to minimize audible noise emitted by the EL Lamps.
