Operating temperature range is as follows: –40 C to +85 C. Therefore, T
Test conditions: Input PGA set for 0 dB gain, Output PGA set for 6 dB gain, no load on analog outputs (unless otherwise noted).
At input to sigma-delta modulator of ADC.
Guaranteed by design.
Overall group delay will be affected by the sample rate and the external digital filtering.
The ADC’s input impedance is inversely proportional to DMCLK and is approximated by: (3.3
Between VOUTP1 and VOUTN1 or between VOUTP2 and VOUTN2.
At VOUT output.
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.
Test Conditions: no load on digital inputs, analog inputs ac coupled to ground, no load on analog outputs.
