DESCRIPTION
Supply
Operates From 10 V to 26 V
The TPA3121D2 is a 15-W (per channel), efficient,
class-D audio power amplifier for driving stereo
Can Run From +24 V LCD Backlight Supply
speakers in a single-ended configuration or a mono
Efficient Class-D Operation Eliminates Need
speaker in a bridge-tied-load configuration. The
for Heat Sinks
TPA3121D2 can drive stereo speakers as low as 4
.
Four Selectable, Fixed-Gain Settings
The efficiency of the TPA3121D2 eliminates the need
for an external heat sink when playing music.
Internal Oscillator to Set Class D Frequency
(No External Components Required)
The gain of the amplifier is controlled by two gain
select pins. The gain selections are 20, 26, 32, and
Single-Ended Analog Inputs
36 dB.
Thermal and Short-Circuit Protection With
Auto Recovery
The patented start-up and shutdown sequences
minimize pop noise in the speakers without additional
Space-Saving Surface Mount 24-Pin TSSOP
circuitry.
