HM2012

2.1W/ch Stereo Filter-free Class-D Audio Power Amplifier

General Description

Personal Digital Assistant(PDA)

Portable gaming device

Powered speakers

The HM2012 is a 2.1W/ch stereo high efficiency

filter-free class-D audio power amplifier. The HM2012

can operate from 2.7 to 5.5V supply. When powered

with 5V voltage, the HM2012 can deliver 2.1W per

channel to dual 4Ω load at 10% THD+N, and also

capable of driving 1.5W/ch to dual 8Ω load. The

HM2012 is thermally limited in WCSP and may not

achieve 2.1W/ch for 4Ω.

Features

Output power

– 2.1W/ch into 4Ω at 5V

– 1.5W/ch into 8Ω at 5V

As a Class D audio power amplifier, the HM2012

supports 90% high efficiency and -75dB PSRR at

217Hz which make the device ideal for

battery-supplied, high quality audio applications.

The HM2012 features independent shutdown controls

for each channel. The gain can be selected to 6, 12,

18, or 24 dB utilizing the G0 and G1 gain select pins.

The HM2012 also features the minimized

click-and-pop noise during the turn-on and

shutdown.

– 750mW/ch into 8Ω at 3.6V

PSRR: -75dB (typical)

CMRR: -70dB (typical)

Efficiency up to 90%

Only two external components required

Independent shutdown control for each channel
