Features
1) 4-channel BTL driver
2) Set space saving by adoption of HSOP28
3) Built-in OP amp.
4) Wide dynamic range
5) Built-in thermal shutdown circuit
6) High efficient supply voltage setting due to independent supply
(Pre Vcc, Pow Vcc of CH1, CH2 and Pow Vcc of CH3, CH4)
7) For CH4, input pin can be switched by SW pin
