SLOS661A –DECEMBER 2011–REVISED APRIL 2012

3-W Mono Class-D Audio Amplifier With SmartGain™ AGC/DRC

Check for Samples: TPA2029D1

FEATURES

DESCRIPTION

The TPA2029D1 is a mono, filter-free Class-D audio

power amplifier with dynamic range compression

(DRC) and automatic gain control (AGC). It is

available in a 1.63 mm x 1.63 mm WCSP package.

•

Filter-Free Class-D Architecture

3 W Into 4 Ω at 5 V (10% THD+N)

880 mW Into 8 Ω at 3.6 V (10% THD+N)

Power Supply Range: 2.5 V to 5.5 V

3 Selectable AGC functions

Low Supply Current: 1.8 mA

Low Shutdown Current: 0.2 μA

High PSRR: 80 dB

The DRC/AGC function in the TPA2029D1 can be

enabled and disabled. The DRC/AGC function is

configured to automatically prevent distortion of the

audio signal and enhance quiet passages that are

normally not heard. The DRC/AGC is also configured

to protect the speaker from damage at high power

levels and compress the dynamic range of music to fit

within the dynamic range of the speaker. The

TPA2029D1 is capable of driving 3 W at 5 V into 4Ω

load or 880 mW at 3.6 V into 8Ω load. The device

features an enable pin and also provides thermal and

short circuit protection.

Fast Start-up Time: 5 ms

AGC Enable/Disable Function

Limiter Enable/Disable Function

Short-Circuit and Thermal Protection

Space-Saving Package

In addition to these features, a fast start-up time and

small package size make the TPA2029D1 an ideal

choice for Notebook PCs, PDAs and other portable

applications.
