• Description: Universal Serial Bus Usb Digital-to-analog Converter Dac
• Manufacturer: NXP Semiconductors

Philips Semiconductors
Notes
1. A 3rd overtone crystal of 48 MHz must be used in combination with a filter connected to the oscillator output (XTAL2),
2. Strongly depends on the external decoupling capacitor connected to V
3. Use for calculation of the power-on reset set-up time the C
4. The audio information from the USB interface is fed directly to the ADAC.
APPLICATION INFORMATION
The UDA1321 is designed to be used as a self-powered device.
The I
customers with defining there own configuration map, a special program called ‘Configuration map editor’ has been
developed. It is available from your local Philips Semiconductors Field Application Engineer.
More information about the firmware, descriptors and configurations can be obtained from several application notes.
