DESCRIPTION
Operates from 10 V to 30 V
The TPA3123D2 is a 25-W (per channel) efficient,
Efficient Class-D Operation Eliminates Need
Class-D audio power amplifier for driving stereo
for Heat Sinks
speakers in a single-ended configuration or a mono
Four Selectable, Fixed-Gain Settings
speaker in a bridge-tied-load configuration. The
Internal Oscillator (No External Components
TPA3123D2 can drive stereo speakers as low as 4
.
The efficiency of the TPA3123D2 eliminates the need
Required)
for an external heat sink when playing music.
Single-Ended Analog Inputs
The gain of the amplifier is controlled by two gain
Thermal and Short-Circuit Protection With
select pins. The gain selections are 20, 26, 32,
Auto Recovery
36 dB.
Space-Saving Surface-Mount 24-Pin TSSOP
The patented start-up and shut-down sequences
Package
minimize pop noise in the speakers without additional
Pin-to-Pin compatible with TPA3120D2
circuitry.
Advanced Power-Off Pop Reduction
