1 Operating temperature range is as follows: –40°C to +85°C. Therefore, T
2 Test conditions: Input PGA set for 0 dB gain (unless otherwise noted).
3 At input to sigma-delta modulator of ADC.

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: (4 × 10
7 Frequency response of the ADC measured with input at audio reference level (the input level that produces an output level of 0 dBm0), with 38 dB preamplifier
bypassed and input gain of 0 dB.
8 Test Conditions: no load on digital inputs, analog inputs ac-coupled to ground.
