Package
Shutdown Mode
Typical Power Output at 5V,
1% THD+N
.
A SD_MODE select pin determines the Shutdown Mode for the LD and MH packages, whether it is an Asserted High or an Asserted Low device, to activate
shutdown.
.
The SD_MODE select pin is not available with the MM and ITL packaged devices. Shutdown occurs only with a low assertion.
