Default TE7022+ES9023 mini toy^_^

Hi, guys. I made this toy these days. ES9023 is 113dB DAC and work in I2S mode. The output has no coupled caps and up to 2Vrms. Here it is.

Yep, I am interested, is that going to be available in PCB or full kit? I still have 2 9023 sitting around.

Hi, i2k92. I already made some and Steinar will post it after testing. And hi syklab, I can make some without es9023.
For portable use, es9023 is a good choise, it's single power supply and no-coupled capacitor needed, that means it's also suitable to add a potentiometer at the output... It's another product then.

And hi all, I have a question now. The datasheet of ES9023 says it can adjust the output level by an external resistor, anyone knows how? Thanks.

Never mind, I already got it. A resistor on Vreg pin will adjust the level.

I got one through ebay a couple of days ago. I like it best with my headphones directly plugged in.

Small size and no extra power supply or batteries needed. Marvelous portability.

Audiophile quality at less than $50 including the postage. Great bargain!

Well done HiFimedDIY.
