Other Parts Discussed in Thread: TAS5766M, TAS5754M
Hello,
Our customer plans to use TAS5756M for AI speaker.
During no sound output situation, they want to move Power Save Modes to extend battery life.
TAS5766M is family device and there is description on datasheet as below.
Can we expect TAS5756M has same functionality?
Regards,

8.4.7.7 Power Save Modes
The TAS576xM offers two power-save modes; standby and power-down.
When a clock error (SCLK, BCLK, and LRCLK) or clock halt is detected, the TAS576xM automatically enters
standby mode. The DAC and power amplifier are also powered down. The device can also be placed in standby
mode via software command.
When BCLK and LRCLK remain at a low level for more than 1 second, the TAS576xM automatically enters
power-down mode. Power-down mode disables the negative charge pump and bias/reference circuit, in addition
to those disabled in standby mode. The device can also be placed in power-down mode via I2C command.
When expected Audio clocks (SCLK, BCLK, LRCLK) are applied to the TAS576xM, the device starts its powerup
sequence automatically.
