TAS5765M Power Dissipation in "Powerdown"



The TAS5765M data sheet states that it dissipates 0.212 Watts (24V, 384KHz, 8 Ohms) and draws 8mA Ipvdd and 1mA Ipdvdd in "powerdown". Is "powerdown" its lowest power dissipation state? Or, is this the power-save mode?  I'm asking because I'm considering a design in which PVDD will constantly be at 24V, but external circuitry will handle power ON/OFF, will produce the muting control signals, etc. This is an 8-channel product, so the combined dissipation of 4 chips would be nearly 1 Watt, unless there is a lower-power state I can use. Thanks.
