AT8031
AT8031 is a single-chip 2.1 channel class D amplifier with three built-in channels of class D amplifier, with more than 90% efficiency, no need to use external heat sink, the peripheral circuit is extremely simple.
AT8031 can support the power supply voltage range of 5V~16V, each channel adopts the output mode of BTL, under the condition of the left and right channel 8 ohm load, the bass channel 4 ohm load, the maximum can provide 2*10W+20W output power, PBTL design can be left and right two small power channels and combine into one channel. Combined with the bass channel to form a 2*20W stereo amplifier.
The AT8031 is available in an e-TSSOP24 package.
