SLOSE75B February 2022 – March 2023 TAS2780
PRODUCTION DATA
Software Shutdown mode powers down all analog blocks required to playback audio, but does not cause the device to lose register state.
The registers are available through I2C interface.
Software Shutdown is enabled by asserting the MODE[2:0] register bits to 3'b010. If audio is playing when Software Shutdown is asserted, the Class-D will volume ramp down before shutting down. When de-asserted, the Class-D will begin switching and volume will ramp back to the programmed digital volume setting.
