1. CHARACTERISTICS AND SPECIFICATIONS
ANALOG CHARACTERISTICS (Standard test conditions unless otherwise noted: T
ambient = 25° C,
AVdd = 5.0 V ±5%, DVdd = 3.3 V ±5%; 1 kHz Input Sine wave; Sample Frequency, Fs = 48 kHz; ZAL=100 kΩ/
1000 pF load for Mono and Line Outputs; CDL = 18 pF load (Note 1); Measurement bandwidth is 20 Hz - 20 kHz,
18-bit linear coding for ADC functions, 20-bit linear coding for DAC functions; Mixer registers set for unity gain.
Notes: 1. ZAL refers to the analog output pin loading and CDL refers to the digital output pin loading.
2. Parameter definitions are given in Section 13, Parameter and Term Definitions.
3. Path refers to the signal path used to generate this data. These paths are defined in Section 13,
Parameter and Term Definitions.
4. This specification is guaranteed by silicon characterization; it is not production tested.
