DC CHARACTERISTICS
VDDD =VDDA =VDDO = 5 V; Tamb =25 °C; all voltages referenced to ground (pins 2, 9 and 23); unless otherwise
specified.
Notes
1. All power supply pins (VDD and VSS) must be connected to the same external power supply unit.
2. RL is the AC resistance of the external circuitry connected to the audio outputs of the application circuit.
