Part Number: DRV603

Hi Team,

customer would like to design DRV603 in TV to driver line out or headphone out.

Would you please review schematic/questions and provide your comment?

(1)can DRV603 support headphone output 5mW with Load 32Ω?

(2)can DRV603 support lineout 2Vrms with Load 10KΩ?

Thanks for help.

HI SHH,

First case put out breaks spec with minimum load impedance supported.

Such a large load could affect gain performance in case 2 but device can still handle it.

Best Regards,

Carson

Hi Carson,

thanks. do you have any concern on the schematic?

Can DRV603 support the 1st case?

I have no real concern with schematic besides the two different cases you present are a little irregular but case1 would most likely not be able to be handled by device and case 2 doesnt seem like you would be getting enough current flow for device to be used efficiently.

Best Regards,

Carson
