Part Is Functional with Lower VREF Voltages Input Sampling Rate, fS fCLK IN/256 NOTES 1Temperature ranges are as follows: A Version, –40 °C to +85°C; S Version, –55°C to +125°C. See also Note 16. 2Applies after calibration at the temperature of interest. 3Positive full-scale error applies to both unipolar and bipolar input ranges. 4These errors will be of the order of the output noise of the part as shown in Table I after system calibration. These errors will be 20 µV typical after self-calibration or background calibration. 5Recalibration at any temperature or use of the background calibration mode will remove these drift errors. 6This common-mode voltage range is allowed, provided that the input voltage on AIN(+) and AIN(–) does not exceed AV DD + 30 mV and VSS – 30 mV. 7These numbers are guaranteed by design and/or characterization. 8The analog inputs present a very high impedance dynamic load that varies with clock frequency and input sample rate. The maximum recommended source resistance depends on the selected gain (see Tables IV and V). 9The analog input voltage range on the AIN1(+) and AIN2(+) inputs is given here with respect to the voltage on the AIN1(–) and AIN2(–) inputs. The absolute voltage on the analog inputs should not go more positive than AV DD + 30 mV or go more negative than VSS – 30 mV. 10V REF = REF IN(+) – REF IN(–). 11The reference input voltage range may be restricted by the input voltage range requirement on the V BIAS input. AD7710–SPECIFICATIONS (AV DD = +5 V 5%; DVDD = +5 V 5%; VSS = 0 V or –5 V 5%; REF IN(+) = +2.5 V; REF IN(–) = AGND; MCLK IN = 10 MHz unless otherwise noted. All specifications TMIN to TMAX, unless otherwise noted.) |
