4-channel BTL driver for CD players
BA5948FP
BA5948FP is a 4-channel BTL driver for CD players. The adoption of HSOP28 package enables to make sets smaller.
This IC incorporates thermal shutdown circuit and mute function with two mute pins. Gain can be controlled by external
resistor in driver block.
