GENERAL DESCRIPTION
The UDA1320ATS/N2 is a single-chip non inverting stereo
DAC employing bitstream conversion techniques. The low
power consumption and low voltage requirements make
the device eminently suitable for use in digital audio
equipment which incorporates playback functions.
• Slave mode only applications.
• Small package size (SSOP16).
1.2
Multiple format input interface
• I2S-bus, MSB-justified and LSB-justified 16,18 and 20
bits format compatible (in L3-mode).
The UDA1320ATS/N2 supports the I2S-bus data format
with word lengths of up to 20 bits, the MSB-justified data
format with word lengths of up to 20 bits and the
LSB-justified serial data format with word lengths of 16,
18 and 20 bits.
• I2S-bus and LSB-justified 16,18 and 20 bits format
compatible in static mode.
• 1fs input format data rate.
The UDA1320ATS/N2 can be used in two modes, either
L3-mode or static pin mode.
1.3
DAC digital sound processing
• Digital logarithmic volume control via L3.
In the L3-mode, all digital sound processing features must
be controlled via the L3 interface, including the selection of
the system clock setting.
• Digital de-emphasis for 32, 44.1 and 48 kHz fs via
L3 or 44.1 kHz fs via static pin control.
In the two static-modes, the UDA1320ATS/N2 can be
operated in the 256fs and 384fs system clock mode. The
mute, de-emphasis for 44.1 kHz and 4 digital input formats
(I2S and 16, 18, 20 bits LSB formats) can be selected via
static pins. The L3 interface cannot be used in this
application mode, also, volume control is not available in
this mode.
• Soft mute via static pin control or via L3 interface.
1.4

Multiple format input interface
IMPORTANT: UDA1320ATS/N2 differs from the
UDA1320TZ/N1 with respect to:
L3 mode:
•
•
in the static mode 384fs is supported instead of 512fs.
• I2S-bus with data word length of up to 20 bits
the output voltage of the DAC. In the UDA1320TZ/N1
this is 800mVrms at 3.0V, now it is 1Vrms at 3.3V power
supply
• MSB-justified format with data word length up to 20 bits
• LSB-justified format with data word length of 16,
18 or 20 bits.
8.6
Interpolation filter (DAC)
8.4
Static pin mode
The digital filter interpolates from 1 to 128fs by cascading
a recursive filter and a FIR filter, see Table 3.
The UDA1320ATS/N2 supports the following data input
name formats in the static pin mode (via SF0 and SF1):
• I2S bus with data word length of up to 20 bits
Table 3 Interpolation filter characteristics
• LSB-justified format with data word length of 16,
18 or 20 bits.

The UDA1320ATS/N2 also accepts double speed data for
double speed data monitoring purposes.
8.7
Noise shaper
The 3rd-order noise shaper operates at 128fs. It shifts
in-band quantization noise to frequencies well above the
audio band. This noise shaping technique enables high
signal-to-noise ratios to be achieved. The noise shaper
output is converted into an analog signal using a
Filter-Stream DAC (FSDAC).

Filter-Stream DAC
The FSDAC is a semi-digital reconstruction filter that
converts the 1-bit data stream of the noise shaper to be
analog output voltage. The filter coefficients are
implemented as current sources and are summed at
virtual ground of the output operational amplifier. In this
way very high signal-to-noise performance and low clock
jitter sensitivity is achieved. A post-filter is not needed due
to the inherent filter function of the DAC. On-board
amplifiers convert the FSDAC output current to an output
voltage signal capable of driving a line output.
The formats are illustrated in Fig.3. Left and right
data-channel words are time multiplexed. The WS signal
must have 50% duty-factor for all LSB-justified modes.
For BCK and WS holds that the BCK frequency must be
equal or smaller then 64 times WS, or fBCK =< 64*fWS in
both L3 and static mode.
8.5
Pin compatibility
In L3 interface mode the UDA1320ATS/N2 can be used on
boards that are designed for the UDA1322. The software
for UDA1322 can be used for the UDA1320ATS/N2 to
control de-emphasis, volume control and mute and also
the status settings like system clock setting and input data
format.
The output voltage of the FSDAC scales linearly with the
power supply voltage.

L3 INTERFACE DESCRIPTION
The L3 interface
Data transfer can only be in one direction, consisting of
input to the UDA1320ATS/N2 to program sound
processing and other functional features.
9.1
The following system and digital sound processing
features can be controlled in the microcontroller mode of
the UDA1320ATS/N2:
Data bits 7 to 2 represent a 6-bit device address, bit 7
being the MSB. The address of the UDA1320ATS/N2 is
000101 (bit 7 to bit 2). If the UDA1320ATS/N2 receives a
different address, it will deselect its microcontroller
interface logic.
• System clock frequency
• Data input format
• De-emphasis for 32 kHz, 44.1 kHz and 48 kHz
• Volume
9.2
Data transfer mode
The selected address remains active during subsequent
data transfers until the UDA1320ATS/N2 receives a new
address command. The fundamental timing of data
transfers is essentially the same as in the address mode,
see Fig.6. The maximum input clock and data rate is 64 fs.
All transfers are by 8-bit bytes. Data will be stored in the
UDA1320ATS/N2 after reception of a complete byte. See
Fig.5 for a multi-byte transfer.
• Soft mute.
The exchange of data and control information between the
microcontroller and the UDA1320ATS/N2 is accomplished
through a serial hardware interface comprising the
following pins:
• L3DATA
• L3MODE
• L3CLOCK.
Table 4 Selection of data transfer
Information transfer through the microcontroller bus is
organized in accordance with the L3 format, in which two
different modes of operation can be distinguished; address
mode and data transfer mode (see Figs 4 and 6).

The sound feature values are stored in independent
registers. The first selection of the registers is achieved by
the choice of data type that is transferred (‘STATUS’ or
‘DATA’ transfer). This is performed in the address mode
using bit 1 and bit 0, see Table 4,. The settings that can be
controlled with ‘STATUS’ transfer are given in table 5, and
the settings that can be controlled using ‘DATA’ transfer
are given in table 6.
The second selection is performed by the 2 MSBs of the
data byte (bit 7 and bit 6). The other bits in the data byte
(bit 5 to bit 0) is the value that is placed in the selected
registers.

18 SOLDERING
• Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.
18.1 Introduction to soldering surface mount
packages
• For packages with leads on two sides and a pitch (e):
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our “Data Handbook IC26; Integrated Circuit Packages”
(document order number 9398 652 90011).
– larger than or equal to 1.27 mm, the footprint
longitudinal axis is preferred to be parallel to the
transport direction of the printed-circuit board;
– smaller than 1.27 mm, the footprint longitudinal axis
must be parallel to the transport direction of the
printed-circuit board.
There is no soldering method that is ideal for all surface
mount IC packages. Wave soldering is not always suitable
for surface mount ICs, or for printed-circuit boards with
high population densities. In these situations reflow
soldering is often used.
The footprint must incorporate solder thieves at the
downstream end.
• For packages with leads on four sides, the footprint must
be placed at a 45° angle to the transport direction of the
printed-circuit board. The footprint must incorporate
solder thieves downstream and at the side corners.
18.2 Reflow soldering
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.
During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.
Several methods exist for reflowing; for example,
infrared/convection heating in a conveyor type oven.
Throughput times (preheating, soldering and cooling) vary
between 100 and 200 seconds depending on heating
method.
Typical dwell time is 4 seconds at 250 °C.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
Typical reflow peak temperatures range from
215 to 250 °C. The top-surface temperature of the
packages should preferable be kept below 230 °C.
18.4 Manual soldering
Fix the component by first soldering two
diagonally-opposite end leads. Use a low voltage (24 V or
less) soldering iron applied to the flat part of the lead.
Contact time must be limited to 10 seconds at up to
300 °C.
18.3 Wave soldering
Conventional single wave soldering is not recommended
for surface mount devices (SMDs) or printed-circuit boards
with a high component density, as solder bridging and
non-wetting can present major problems.
When using a dedicated tool, all other leads can be
soldered in one operation within 2 to 5 seconds between
270 and 320 °C.
To overcome these problems the double-wave soldering
method was specifically developed.
If wave soldering is used the following conditions must be
observed for optimal results:

Notes
1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum
temperature (with respect to time) and body size of the package, there is a risk that internal or external package
cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the
Drypack information in the “Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods”.
2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink
(at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version).
3. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction.
The package footprint must incorporate solder thieves downstream and at the side corners.
4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm;
it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.
5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is
definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
