NOTES
1 Operating temperature range is as follows: –40°C to +85°C. Therefore, TMIN = –40°C and TMAX = +85°C.
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 × 1011)/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.
10Test Conditions: no load on digital inputs, analog inputs ac coupled to ground, no load on analog outputs.
Specifications subject to change without notice.
