ماژول آمپلی فایر PAM8403 با پایه کنترل

ماژول آمپلی فایر PAM8403 با پایه کنترل

• دارای قابلیت کنترل صدا و فعال/غیر فعال سازی ماژول:

Mute Operation:

The MUTE pin is an input for controlling the output state of the PAM8403. A logic low on his pin disables the outputs, and a logic high on this pin enables the outputs. This pin may be used as a quick disable or enable of the outputs without a volume fade. Quiescent current is listed in the electrical characteristic table. The MUTE pin can be left floating due to the pull-up internal

Shutdown operation:

In order to reduce power consumption while not in use, the PAM8403 contains shutdown circuitry that is used to turn off the amplifier's bias circuitry. This shutdown feature turns the amplifier off when logic low is placed on the.SHDN pin. By switching the SHDN pin connected to GND, the PAM8403 supply current draw will be minimized in idle mode. The SHDN pin can be left floating due to the pull-up internal
