ML22Q553

Handling of the SG Pin

The SG pin is the signal ground pin for the built-in speaker amplifier.

Connect a capacitor between this pin and

the analog ground so that this pin will not carry noise.

The recommended capacitance value is shown below; however, it is recommended that the user determine the

capacitance value after evaluation.

Always start playback after each output voltage is stabilized.

Recommended

capacitance value

Remarks

0.1

μF ±20%

The larger the connection capacitance, the longer the speaker

amplifier output pin (SPM and SPP) voltage stabilization time.

Handling of the VDDL and VDDR Pins

The VDDL and VDDR pins are the power supply pins for the internal circuits.

Connect a capacitor between each

of these pins and the ground in order to prevent noise generation and power fluctuation.

The recommended capacitance value is shown below; however, it is recommended that the user determine the

capacitance value after evaluation.

Always start the next operation after each output voltage is stabilized.

Recommended

capacitance value

Remarks

VDDL, VDDR

μF ±20%

The larger the connection capacitance, the longer the

stabilization time.
