Speaker and 12V Power supply

• Built-in 2 channels (dual) enabling use in stereo and bridge amplifier applications.

Dual : 6W×2 (typ.) Bridge : 19W (typ.)

• Minimum number of external parts required.

• Small pop noise at the time of power supply ON/OFF and good starting balance.

• Good ripple rejection : 46dB (typ.)

• Good channel separation.

• Small residual noise (Rg=0).

• Low distortion over a wide range from low frequencies to high frequencies.

• Easy to design radiator fin.

• Built-in audio muting function.

• Built-in protectors. a. Thermal protector b. Overvoltage, surge voltage protector c. Pin-to-pin short protector
