MP7721

2 x 10W Class D Stereo

Single Ended Audio Amplifer

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP7721 is a stereo 2 x 10W Class D Audio

Amplifier. It is one of MPS’ second generation

fully integrated audio amplifiers which

dramatically reduces solution size by integrating

the following:

•

2 x 10W Output at V_DD= 24V into a 8Ω load

THD+N = 0.06% at 1W, 8Ω

93% Efficiency at 10W

Low Noise (190µV Typical)

Switching Frequency Up to 1MHz

9.5V to 24V Operation from a Single Supply

Integrated Startup and Shutdown Pop

Elimination Circuit

Thermal and Short Circuit Protection

Integrated 250mΩ Switches

Mute/Standby Modes (Sleep)

Thermally Enhanced 20-Pin TSSOP

Package with Exposed Pad

250mΩ power MOSFETs

Startup / Shutdown pop elimination

Short circuit protection

Mute / Standby

•

The MP7721 utilizes a single ended output

structure capable of delivering 2 x 10W into 8Ω

speakers. MPS Class D Audio Amplifiers exhibit

the high fidelity of a Class A/B amplifier at

efficiencies greater than 90%. The circuit is

based on the MPS’ proprietary variable

frequency topology that delivers low distortion,

fast response time and operates on a single

power supply.
