APA2011/2011A

2.8W Mono Class D Audio Power Amplifier with AGC

Features

General Description

Operating Voltage: 2.4V-5.5V

High Efficiencyup to 90%

SupplyCurrent

The APA2011/2011A is a mono, filter-free Class-D audio

amplifier available in WLCSP1.5x1.5-9 or TDFN3x3-8

package.

– I_DD=3mA at V_DD=5V

– I_DD=2.5mA at V_DD=3.6V

Low Shutdown Current

– I_DD=1mA at V_DD=5V

The default gains without the external input resistor is

27dB. Besides, the gain can be low down by external

input resistance. APA2011 provides an Dynamic-Range-

Control (DRC) function, and this function can low down

the dynamic range for large input signal. APA2011 can

provide maximun 15dB gain control. APA2011A can pro-

vide maximum 15dB gain decrease for non-clipping

function, and this function can avoid output signal clipping.

High PSRR and differential architecture provide increased

immunity to noise and RF rectification. In addition to these

features, a fast start-up time and small package size

make the APA2011/2011A an ideal choice for portable

devices.

Output Power

at 1%THD+N

– 1.3W, at V_DD=5V, R_L=8W

– 0.6W, at V_DD=3.6V, R_L=8W

– 2.0W, at V_DD=5V, R_L=4W

– 1.0W, at V_DD=3.6V, R_L=4W

at 10%THD+N

– 1.6W, at V_DD=5V, R_L=8W

– 0.8W, at V_DD=3.6V, R_L=8W

– 2.8W, at V_DD=5V, R_L=4W (WLCSP-9)

– 2.4W, at V_DD=5V, R_L=4W

The APA2011/2011A is capable of driving 1.6W at 5V or

0.8W at 3.6V into 8W. It is also capable of driving 4W. The

APA2011/2011A is designed with a Class-D architecture

and operating with highly efficiency compared with Class-

AB amplifier. It’s suitable for power sensitive application,

such as battery-powered devices. The filter-free architec-

ture eliminates the output filter, reduces the external com-

ponent count, board area, and system costs, and simpli-

fies the design.

– 1.2W, at V_DD=3.6V, R_L=4W

APA2011 Dynamic Range Control (DRC) Provide

Maximum 15dB Control (2:1 Compression Ratio)

APA2011A Non-Clip Function can Provide Maxi-

mum 15dB Control (Gain Decreasing)

Less External Components Required

Fast Start-up Time (4ms)

High PSRR: 70dB at 217Hz

Moreover, the APA2011/2011A provides thermal and short

circuit protection.
