Monolithic Power Systems Introduces Smallest Dual-Channel 20W Class D Audio Amplifier.

LOS GATOS, Calif. -- Monolithic Power Systems (MPS) (Nasdaq:MPWR) is now shipping the MP7722, an ultra compact 2 x 20W Class D audio amplifier. Delivering 20W into 4 Ohms (10% THD) and integrating four 180 mOhm MOSFETs, the MP7722 achieves 93% efficiency at full output power. Available in a small TSSOP package, the MP7722 is the most compact solution in its class.

The MP7722 features a unique closed loop topology that provides excellent linearity with a very low THD+N of 0.06% at 1kHz. MPS' proprietary variable switching frequency topology reduces the magnitude of EMI spikes during operation. Other features include adjustable gain via two external resistors, power-on/off pop & click suppression and thermal/short circuit protection. In addition, the MP7722 incorporates mute and standby modes for lower power consumption.

Samples and evaluation boards are available immediately. Pricing for the MP7722 begins at $2.90 in 1k piece quantities.
