UDA1330ATS: Low-cost stereo filter DAC ARCHIVED

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 256f_s, 384f_s and 512f_s selectable via L3 interface or 256f_s and 384f_s via static pin control
• Supports sampling frequencies (f_s) from 8 to 55 kHz
• Integrated digital filter plus non-inverting
• Digital-to-Analog Converter (DAC)
• No analog post filtering required for DAC
• Slave mode only applications
• Easy application
• Small package size (SSOP16)
• TTL tolerant input pads
• Pin and function compatible with the UDA1320ATS

Multiple format input interfaces

• L3 mode: I²S-bus, MSB-justified or LSB-justified 16, 18 and 20 bits format compatible
• Static pin mode: I²S-bus and LSB-justified 16, 18 and 20 bits format compatible
• 1f_s input format data rate

DAC digital sound processing

• Digital logarithmic volume control in L3 mode
• Digital de-emphasis for 32, 44.1 and 48 kHz sampling frequencies in L3 mode or 44.1 kHz sampling frequency in static pin mode
• Soft mute control both in static pin mode and L3 mode

Advanced audio configuration

• Stereo line output (volume control in L3 mode)
• High linearity, wide dynamic range, and low distortion
