MP7748

2x20W Stereo Single Ended

Class D Audio Amplifier

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP7748 is a Class D Audio Amplifier for

driving stereo speakers in single-ended

configuration or a mono speaker in bridge-tied-

load configuration. It is fully integrated audio

amplifier which dramatically reduces solution

size by integrating the following:

•

Output Power at 24V VDD and 10%

THD+N

• Stereo SE configuration: 20W per channel

into 4Ω load

• Mono BTL configuration: 50W into 6Ω

load

•

250mΩ power MOSFETs

•

THD+N = 0.02% at 1W, 8Ω(SE)

Low Noise (103µV with SE configuration,

140µV with BTL configuration)

Switching Frequency Up to 1MHz

9.5V to 36V Operation from a Single

Supply

Integrated Startup and Shutdown Pop

Elimination Circuit

Programmable UVP

Startup / Shutdown pop elimination

Short circuit protection circuits

•

The MP7748 is capable of delivering 20W per

channel into 4Ω speaker in single-ended output

structure, or delivering 50W into 6Ω speaker in

bridge-tied-load output structure under 24V

VDD. 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.

•

Thermal and Short Circuit Protection

Integrated Power FETs

Available in TSSOP28-Exposed Package

shutdown voltage for each channel by

controlling the UVP node voltage. The default

VDD shutdown (rising threshold) voltage is 8.4V

if the UVP pin is NC.
