General
• Low power consumption
• Power supply voltage from 2.7 to 5.5 V
• Selectable control via L3 microcontroller interface or via
static pin control
• System clock frequencies of 256fs, 384fs and 512fs
selectable via L3 interface or 256fs and 384fs via static
pin control APPLICATIONS • Supports sampling frequencies (fs) from 8 to 55 kHz • PC audio applications • Integrated digital filter plus non inverting
Digital-to-Analog Converter (DAC) • Car radio applications. • No analog post filtering required for DAC GENERAL DESCRIPTION • Slave mode only applications The UDA1330ATS is a single-chip stereo DAC employing
bitstream conversion techniques. • Easy application
• Small package size (SSOP16) The UDA1330ATS 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. • TTL tolerant input pads
• Pin and function compatible with the UDA1320ATS.
Multiple format input interface The UDA1330ATS can be used in two modes: L3 mode or
the static pin mode. • L3 mode: I2S-bus, MSB-justified or LSB-justified
16, 18 and 20 bits format compatible In the L3 mode, all digital sound processing features must
be controlled via the L3 interface, including the selection of …
