3W ANTI-CLIP CLASS-D AUDIO POWER AMPLIFIER

VREF terminal output

The voltage of V_DD/2 is output from the V_REFterminal. Capacitor (1uF) is connected between the V_REFterminal and

GND for stabilization.

Power down and Initialization function

When CTRL terminal is connected to the GND potential, the IC goes to the power-down mode. In the mode, all the

circuit functions stop and its current consumption becomes the lowest.

When CTRL terminal is set to H level, the power-down mode is canceled and the IC starts up after startup time

(t_STUP).

In order to return from the power-down mode a desired mode needs to be set after setting both CTRL1 and CTRL2 to

H level during t_WK. In addition, at startup, cancel the power-down mode after supply voltages has been sufficiently

stabilized.

CTRL terminal function

By connection external resistors (Rctrl1, Rctrl2, and Rctrl3: Accuracy of 1%) to CTRL terminal, and impression

setting threshold voltage of each mode to CTRL terminal, the followings can be set: Anti-Clip1, Anti-Clip2, Anti-Clip

OFF, and power-down mode. When turning on the supply voltage or cancelling the power-down mode, control the

CTRL terminal according to the procedure for cancelling power-down.

Connect the terminal to the ground through a capacitor Cctrl (a ceramic capacitor of 0.1μF or more)
