UDA1334ATS
2.4 to 3.6 V power supply voltage
On-board PLL to generate the internal system clock:
– Operates as an asynchronous DAC, regenerating the
– Generates audio related system clock (output) based
Integrated digital filter plus DAC
Supports sample frequencies from 16 to 100 kHz in
asynchronous DAC mode
No analog post filtering required for DAC
Easy application
SSOP16 package.

Digital de-emphasis for 44.1 kHz sampling frequency
Mute function.
High linearity, wide dynamic range and low distortion.
Integrated low jitter PLL for use in applications in which
there is digital audio data present but the system cannot
provide an audio related system clock. This mode is
called audio mode.
The PLL can generate 256
from a 27 MHz input clock. This mode is called video
mode.

This audio DAC is excellently suitable for digital audio
portable application, specially in applications in which an
audio related system clock is not present.

The UDA1334ATS is a single chip 2 channel
digital-to-analog converter employing bitstream
conversion techniques, including an on-board PLL.
The extremely low power consumption and low voltage
requirements make the device eminently suitable for use
in low-voltage low-power portable digital audio equipment
which incorporates a playback function.
The UDA1334ATS supports the I
word lengths of up to 24 bits and the LSB-justified serial
data format with word lengths of 16, 20 and 24 bits.
The UDA1334ATS has basic features such as
de-emphasis (44.1 kHz sampling frequency, only
supported in audio mode) and mute.
