1) 4-channel BTL driver
2) Wide dynamic range (4V typical at PreVcc=12V, PowVcc=5V, RL=8)
3) Built-in thermal shut down circuit
4) Separating Vcc into Pre and Power (Power divides into Channel1&2 and Channel 3&4) makes for improved power efficiency, by a lower supply voltage drive
5) Mute operated individually with Channel 4 and Channel 1&2&3
6) All channels are mute in standby mode
7) Suitable for low operation voltage DSP by wide dynamic range pre operational amplifier.
8) Built-in short-brake circuit (Channel 2&3)
