MP7740

15W Class D Mono

Single Ended Audio Amplifer

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP7740 is a mono 15W Class D Audio

Amplifier. It is one of MPS’ products of fully

integrated audio amplifiers which dramatically

reduces solution size by integrating the

following:

•

15W Output at V_DD= 24V into a 4Ω load

THD+N = 0.05% at 1W, 8Ω

90% Efficiency at 15W & V_DD=24V

Low Noise (103µV Typical)

Switching Frequency Up to 1MHz

9.5V to 36V Operation from a Single Supply

Integrated Startup and Shutdown Pop

Elimination Circuit

Thermal and Short Circuit Protection

Integrated Power FETs

250mΩ power MOSFETs

Startup / Shutdown pop elimination

Short circuit protection circuits

•

The MP7740 utilizes a single ended output

structure capable of delivering 15W into 4Ω

speakers. MPS Class D Audio Amplifiers exhibit

the high fidelity of a Class A/B amplifier at high

efficiencies. The circuit is based on the MPS’

proprietary variable frequency topology that

delivers excellent linearity, fast response time

and operates on a single power supply.

Pin Compatible with MP7720

Available in Tiny 8-Pin SOIC Package

APPLICATIONS

•

Portable Docking Stations

Surround Sound DVD Systems

Televisions

Flat Panel Monitors

Multimedia Computers

Home Stereo Systems
