UDA1380TT

Product Summary

The UDA1380TT is a stereo audio coder-decoder, available in TSSOP32 (UDA1380TT) and HVQFN32 (UDA1380HN) packages. All functions and features are identical for both package versions. The UDA1380TT in this document refers to both UDA1380TT and UDA1380HN, unless particularly specified. The front-end of the UDA1380TT is equipped with a stereo line input, which has a PGA control, and a mono microphone input with an LNA and a VGA. The digital decimation filter is equipped with an AGC which can be used in case of voice-recording.
