LOGIC INPUTS VINH, Input High Voltage DVDD – 0.8 DVDD V VINL, Input Low Voltage 0 0.8 V IIH, Input Current –10 +10 µA CIN, Input Capacitance 10 pF LOGIC OUTPUT VOH, Output High Voltage DVDD – 0.4 DVDD 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 3.3 V DVDD 2.7 3.3 V I 10 DD See Table I NOTES 1 Operating temperature range is as follows: –40°C to +85°C. Therefore, TMIN = –40°C and TMAX = +85°C. 2 Test conditions: Input PGA set for 0 dB gain, Output PGA set for 6 dB gain, no load on analog outputs (unless otherwise noted). 3 At input to sigma-delta modulator of ADC. 4 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: (3.3 × 1011)/DMCLK. 7 Between VOUTP1 and VOUTN1 or between VOUTP2 and VOUTN2. 8 At VOUT output. 9 Frequency 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 pream- plifier bypassed and input gain of 0 dB. 10 Test Conditions: no load on digital inputs, analog inputs ac coupled to ground, no load on analog outputs. Specifications subject to change without notice.
