CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the ADSST-EM-3035 features proprietary ESD protection circuitry, permanent damage may occur
on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
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 ADCs input impedance is inversely proportional to DMCLK and is approximated by: (4 ∞10”)/DMCLK.
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
bypassed and input gain of 0 dB.
Test Conditions: no load on digital inputs, analog inputs ac coupled to ground.
