2.6. STAC9200/9200D 3.3V Analog Performance Characteristics
(T_ambient = 25 ºC, AVdd = 3.3V ± 5%, DVdd = 3.3V ± 5%, AVss=DVss=0V; 1 KHz input sine wave; Sample Frequency =
48 KHz; 0 dB = 1 VRMS, 10 KW/50 pF load, Testbench Characterization BW: 20 Hz – 20 KHz, 0 dB settings on all gain
stages)
Min and Max performance targets are not included here, as specific system characteristics, such as layout, routing and
external CODEC component selection, influence the performance of the CODEC. To receive min/max levels for your
system, please send us a unit and IDT will perform a full audio test suite and provide you with the results. Contact IDT
