1. CHARACTERISTICS AND SPECIFICATIONS
ANALOG CHARACTERISTICS Standard test conditions unless otherwise noted: Tambient = 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, 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.
