Features : 
• Driver exclusively for the 4-ch BTL
• HSOP-M28 PIN power package
• A wide dynamic range [PreVcc=8V, PowVcc=5V, 4V(Typ.) when RL=8Ω]
• A built-in thermal shutdown circuit installed.
• The power supplies such as PreVcc, PowVcc of CH1 and CH2, and PowVcc of CH3 and CH4 are supplied independently to achieve an efficient drive.
• The standby mode can be controlled independently in CH1 to 3 and CH4.
• Setting all of CH1-4 to the standby mode leads the entire circuit to the standby mode.
• The driver pre-stage OP-amp features GND-sense and output rail-to-rail to make this IC suitable for a low voltage DSP.
