AD73360L AD73360LA Parameter Min Typ Max Unit Test Conditions/Comments
LOGIC OUTPUT VOH, Output High Voltage VDD – 0.4 VDD V |IOUT| ≤ 100 µA VOL, Output Low Voltage 0 0.4 V |IOUT| ≤ 100 µA Three-State Leakage Current –10 +10 µA POWER SUPPLIES AVDD1, AVDD2 2.7 3.6 V DVDD 2.7 3.6 V I 8 DD See Table I NOTES 1Operating temperature range is as follows: –40°C to +85°C. Therefore, TMIN = –40°C and TMAX = +85°C. 2Test conditions: Input PGA set for 0 dB gain (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. 7Frequency 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. 8Test Conditions: no load on digital inputs, analog inputs ac-coupled to ground. Specifications subject to change without notice.
