2
Test conditions: Input PGA set for 0 dB gain, Output PGA set for 6 dB gain, no load on analog outputs (unless otherwise noted).
3
At input to sigma-delta modulator of ADC.
4
Guaranteed by design.
5
Overall group delay will be affected by the sample rate and the external digital filtering.
6
The ADC’s input impedance is inversely proportional to DMCLK and is approximated by: (3.3

)/DMCLK.
7
Between VOUTP1 and VOUTN1 or between VOUTP2 and VOUTN2.
8
At VOUT output.
9
Frequency responses of ADC and DAC measured with input at audio reference level (the input level that produces an output level of –10 dBm0), with 38 dB pream-
plifier bypassed and input gain of 0 dB.
10
Test Conditions: no load on digital inputs, analog inputs ac coupled to ground, no load on analog outputs.
Specifications subject to change without notice.
