MP7705

12V, 2x5W/2x2.5W Class–D Stereo

Single Ended Audio Amplifier

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP7705 is a stereo 2x5W/2x2.5W Class–D

Audio Amplifier. It is one of MPS’ second

generation fully integrated audio amplifiers

which dramatically reduces solution size by

integrating the following:

•

2x2.5W Output at V_DD= 12V (8Ω load)

2x5W Output at V_DD= 12V (4Ω load)

THD+N = 0.06% at 1W, 8Ω

95% Efficiency at 2.5W

Low Noise (190μV Typical)

Switching Frequency Up to 1MHz

9.5V to 12V Single-Supply Operation

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

z 250mΩ power MOSFETs

z Startup / Shutdown pop elimination

z Short circuit protection

z Mute / Standby

•

The MP7705 utilizes a single ended output

structure capable of delivering 2x5W into 4Ω or

2x2.5W 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.
