The above values are in mA. MCLK = 16.384 MHz; SCLK = 16.384 MHz.
Operating temperature range is as follows: –40°C to +85°C. Therefore, T
Test conditions: Input PGA set for 0 dB gain (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: (4 × 10
Frequency response of ADC measured with input at audio reference level (the input level that produces an output level of –10 dBm0), with 38 dB preamplifier
Test Conditions: no load on digital inputs, analog inputs ac-coupled to ground.
