Description

@thejpster

TI withdrew the TLV320AIC23B, marking it obsolete. This means JLCPCB no longer stock it.

Specifications included:

  • TSSOP package, so you can see the pins and hand-solder it
  • Stereo line-level out
  • Amplified stereo out for headphones (with volume control)
  • Mono microphone input and stereo line-level input (selectable, with bypass and sidetone)
  • I2C control interface
  • I2S digital interface, with host providing BCLK, LRCLK, and DATA.
  • Ran from 12 MHz crystal
  • Supports 16-bit, at 48 kHz and 44.1 kHz

Edit: Experiments show the RP2040 can take in a 12 MHz BCLK and 44.1 kHz or 48 kHz LRCLK, meaning any notes below about PLLs or taking in clocks are moot. Anything that can generate a BCLK up to 12 MHz should be fine - higher is untested.
