GENERAL DESCRIPTION
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
headphonedriveroutput.Theheadphonedriveriscapable
of driving a 16
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 V
REF(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 I
2
C-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 I
2
S-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 I
2
C-bus interface.
