• Description: Low Power Audio Dac
• Manufacturer: NXP Semiconductors

Philips Semiconductors
Notes
1. All supply connections must be made to the same external power supply unit.
2. At 3 V supply voltage, the input pads are TTL compatible. However, at 2.0 V supply voltage no TTL levels can be
3. When the DAC drives a capacitive load above 50 pF, a series resistance of 100
