92HD202
8-CHANNEL HIGH DEFINITION AUDIO CODEC
PC AUDIO
2.3. 92HD202/92HD202D 5 V Analog Performance Characteristics
(Tambient = 25 ºC, AVdd = 5.0 V ± 5%, DVdd = 3.3 V ± 5%, AVss = DVss = 0 V; 1 KHz input sine wave; Sample
Frequency = 48 KHz; 0dB = 1 VRMS, 10 K/ 50 pF load, Testbench Characterization BW: 20 Hz – 20 KHz, 0dB set-
tings 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
for more information.
