NOTES
1Operating temperature range is as follows: –40
°C to +85°C. Therefore, T
MIN = –40
°C and T
MAX = +85
°C.
2Test conditions: Input PGA set for 0 dB gain, Output PGA set for 6 dB gain, no load on analog outputs (unless otherwise noted).
3At input to sigma-delta modulator of ADC.
4Guaranteed by design.
5Overall group delay will be affected by the sample rate and the external digital filtering.
6The ADC’s input impedance is inversely proportional to DMCLK and is approximated by: (4
× 1011)/DMCLK.
7Between VOUTP and VOUTN.
8At VOUT output.
9Frequency 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 preamplifier
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.
