Text: SM8146A EL Driver IC OVERVIEW The SM8146A is a dedicated EL Electro Luminescence driver IC, capable of driving EL sheet up to 30cm2 in size. The EL drive circuit uses a technique that generates smooth sine wave EL drive waveforms without an output resistor, which has the advantage of preventing EL sheet audible noise, eliminating the need for additional peripheral components and a corresponding drop in power efficiency. Also, the EL drive voltage is constant-voltage controlled and is unaffected by supply voltage fluctuations, so that there are no EL brightness
