STAC9202 2-CHANNEL HIGH DEFINITION AUDIO CODEC WITH DUAL DIGITAL MICROPHONE INTERFACES PC AUDIO IDT™ 2-CHANNEL HIGH DEFINITION AUDIO CODEC WITH DUAL DIGITAL MICROPHONE INTERFACES 13 STAC9202 V 1.1 102606 IDT CONFIDENTIAL 2.3. STAC9202 5V 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; 0 dB = 1 VRMS, 10 K Ω / 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. 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.
