Sweet audio amp

[benheck]

Hey I wanted to give you all a head's up about the audio amp I used in the latest Xbox 360 laptop. Here's the parts:

IC Digital Pot 10K 32TP 8DIP X9511WP-ND
IC AMP AUDIO PWR 2W STER 20DIP TPA6021A4N

Worked great, 5 volt supply and the digital potentiometer is super easy to use. Give it a try before the amp becomes non-stock. (it's Digikey)

I'll be the first noob to ask... is there a diagram for this one?

Thanks

Pin 18 is the volume control, which takes DC voltage from 0v to VDD (the supply voltage).

I guess you'd hook VL to ground, and VH to the input voltage, and VW to pin 18 of the audio amp.
