3.2-W/Ch Stereo Class-D Audio Amplifier with Fast Gain Ramp SmartGain™ AGC/DRC

Check for Samples: TPA2026D2

FEATURES

DESCRIPTION

•

Fast AGC Start-up Time: 5 ms

The TPA2026D2 is a stereo, filter-free Class-D audio

power amplifier with volume control, dynamic range

compression (DRC) and automatic gain control

(AGC). It is available in a 2.2 mm x 2.2 mm WCSP

package.

•

Pin-Out Compatible with TPA2016D2

Filter-Free Class-D Architecture

3.2 W/Ch Into 4 Ω at 5 V (10% THD+N)

750 mW/Ch Into 8 Ω at 3.6 V (10% THD+N)

Power Supply Range: 2.5 V to 5.5 V

Flexible Operation With/Without I²C

Programmable DRC/AGC Parameters

Digital I²C Volume Control

The DRC/AGC function in the TPA2026D2 is

programmable via

digital I²C interface. The

DRC/AGC function can be configured to automatically

prevent distortion of the audio signal and enhance

quiet passages that are normally not heard. The

DRC/AGC can also be 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 gain can be

selected from 0 dB to +30 dB in 1-dB steps. The

TPA2026D2 is capable of driving 3.2 W/Ch at 5 V

into an 4-Ω load or 750 mW/Ch at 3.6 V into an 8-Ω

load. The device features independent software

shutdown controls for each channel and also provides

thermal and short circuit protection. The TPA2026D2

has faster AGC gain ramp during start-up than

TPA2026D2.

Selectable Gain from 0 dB to 30 dB in 1-dB

Steps

•

Selectable Attack, Release and Hold Times

4 Selectable Compression Ratios

Low Supply Current: 3.5 mA

Low Shutdown Current: 0.2 mA

High PSRR: 80 dB

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 TPA2026D2 an ideal

choice for cellular handsets, PDAs, and other

portable applications.
