Q: TAS5707 and TAS5602 Idle current by

 
Hello,

Could you let us know following data of TAS5707 and TAS5602;

-Quiescent supply current at 
Condition 1: Idle (no output), PVDD = 16V, RLoad = 4ohm
Condition 1: Idle (no output), PVDD = 16V, RLoad = 8ohm



A: RE: TAS5707 and TAS5602 Idle current

Data measured on EVM:

For the TAS5707 I measured the following current coming from PVDD:

4 ohms: .117A

8 ohms: .116A

Note that this does not include the current going into DVDD which is about 48mA.

For the TAS5602,

4 ohms: .06A

8 ohms: .059A

In both devices, there is almost no change in currents because the output filters are able to block most of the switching frequencies. As Don mentioned earlier, a different filter might cause much higher currents.
