25-W/ch into a 4- Load from a 27-V Supply
20-W/ch into a 4- Load from a 24-V Supply
The TPA3120D2 is a 25-W (per channel) efficient,
Class-D audio power amplifier for driving stereo
Operates from 10 V to 30 V
speakers in a single-ended configuration or a mono
Efficient Class-D Operation Eliminates Need
bridge-tied speaker. The TPA3120D2 can drive
for Heat Sinks
stereo speakers as low as 4
. The efficiency of the
Four Selectable, Fixed-Gain Settings
TPA3120D2 eliminates the need for an external heat
sink when playing music.
Internal Oscillator (No External Components
Required)
The gain of the amplifier is controlled by two gain
select pins. The gain selections are 20, 26, 32,
Single-Ended Analog Inputs
36 dB.
