Monolithic Power Systems Introduces Compact, Single Supply 50W Class D Audio Amplifier

LOS GATOS, Calif.--July 21, 2005--Monolithic Power Systems (MPS) announces the immediate availability of the MP7782, a full bridge Class D audio amplifier. Operating from a single power supply in the range of 9.5 - 24V, the MP7782 can provide up to 50W of continuous output power into a 6 ohm load with up to 90% efficiency. The ambient operating temperature range for the MP7782 is -40 to 85 degrees C making it suitable for a wide range of applications, from home and office entertainment to automotive multimedia and outdoor audio systems.

The MP7782's integrated FETs together with a small TSSOP20 package form a very compact solution. Output gain can be customized by way of external resistors. When not in use, the internal circuitry can be placed into standby mode cutting quiescent current to 2uA. The device also features a closed loop topology that maintains high audio quality despite fluctuations in the power supply rail. This architecture gives rise to an extremely high audio fidelity with a THD+N of 0.06%.

Short circuit and thermal protection are integrated into the MP7782 design. Samples are available from stock immediately. Pricing for the MP7782 begins at $3.48 in 1,000 piece quantities.
