Function
In PWM mode: Digital Power for the PWM Driver. Deliver 1-watt
output power at V
Or,
In Class-AB mode: Analog Power for the Class-AB output. Class-AB
BTL delivers 1-watt output power at V
PWM driver positive output. This SPK+ output, together with SPK-
pin, provide a differential output to drive 8 speaker or buzzer.
During power down this pin is in tri-state.
Or, can be configured as Class-AB BTL which, together with SPK-
pin, provides a differential voltage output.
Or, can be configured as a Class-AB single-ended output.
In PWM mode: Digital Ground for the PWM Driver.
Or,
In Class-AB mode: Analog Ground for the Class-AB output.
PWM driver negative output. This SPK- output, together with SPK+
pin, provides a differential output to drive 8 speaker or buzzer.
During power down this pin is tri-state.
Or, can be configured as Class-AB BTL which, together with SPK+
pin, provides a differential voltage output.
Or, can be configured as a Class-AB single-ended output.
In PWM mode: Digital Power for the PWM Driver. Deliver 1-watt
output power at V
Or,
In Class-AB mode: Analog Power for the Class-AB output. Class-AB
BTL delivers 1-watt output power at V
This pin should be left unconnected.
This pin should be left unconnected.
This pin should be left unconnected.
Active low interrupt request pin. This pin is an open-drain output.
Can be configured as GPIO3.
An output pin to report the status of data transfer on the SPI
interface. “High” indicates that ISD3800 is ready to accept new SPI
commands or data.
Can be configured as GPIO2.
Applying power to this pin will reset the chip. (A high pulse of 50ms
or more will reset the chip.)
