EV0030 (MP7720DS)

20W Stereo Class D

Single Ended Audio Amplifier

The Future of Analog IC Technology

EVALUATION BOARD

GENERAL DESCRIPTION

FEATURES

The EV0030 is the evaluation board for the

MP7720, a mono 20W Class D Audio Amplifier.

It is one of MPS’ second generation of fully

integrated audio amplifiers which dramatically

reduces solution size by integrating the

following:

•

20W Output at V_DD= 24V into a 4Ω load

THD+N = 0.04% at 1W, 8Ω

93% Efficiency at 20W

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 Protection

Integrated 180mΩ Switches

180mΩ power MOSFETs

Startup / Shutdown pop elimination

Short circuit protection circuits

Mute / Standby

•

Mute/Standby Modes (Sleep)

Available in Tiny 8-Pin SOIC and PDIP Packages

The MP7720 utilizes a single ended output

structure capable of delivering 20W into 4Ω

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’ AAM^TMproprietary variable

frequency topology that delivers excellent

PSRR, fast response time and operates on a

single power supply.
