The UDA1380 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 term ?UDA1380? in this document refers to both UDA1380TT and UDA1380HN, unless particularly specified.
The front-end of the UDA1380 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.
The DAC part is equipped with a stereo line output and a headphone driver output. The headphone driver is capable of driving a 16 Ohm load. The headphone driver is also capable of driving a headphone without the need for external DC decoupling capacitors, since the headphone can be connected to a pin VREF(HP) on the chip.
In addition, there is a built-in short-circuit protection for the headphone driver output which, in case of short-circuit, limits the current through the operational amplifiers and signals the event via its L3-bus or I2C-bus register.
The UDA1380 also supports an application mode in which the coder-decoder itself is not running, but an analog signal, for instance coming from an FM tuner, can be controlled in gain and applied to the output via the headphone driver and line outputs.
The UDA1380 supports the I2S-bus data format with word lengths of up to 24 bits, the MSB-justified data format with word lengths of up to 24 bits and the LSB-justified serial data format with word lengths of 16, 18, 20 or 24 bits (LSB-justified 24 bits is only supported for the output interface).
The UDA1380 has sound processing features in playback mode, de-emphasis, volume, mute, bass boost and treble which can be controlled by the L3-bus or I2C-bus interface.
