    Products Detail

    The LM49250 uses a charge pump to generate a negative supply voltage, enabling ground-biased outputs and eliminating output-coupling capacitors. It integrates an LDO for ground-referenced amplifiers and features fully differential left/right/mono inputs for noise immunity. Inputs can be mixed to loudspeaker, headphone, or earpiece amplifiers. Controlled via I2C, it includes output short-circuit/thermal overload protection and click/pop suppression. Filterless Class D amplifiers deliver 1.19W/channel into 8Ω at 5V with <1% THD+N.
