Note 1: Devices are production tested at +105°C. Specifications to -40°C are guaranteed by design.
Note 2: Tested at VAVDD = VDVDD = +3.0V.
Note 3: Integral nonlinearity is the deviation of the analog value at any code from its ideal value after the offset and gain errors are
removed.
Note 4: Offset nulled.
Note 5: Offset and gain drift defined as change in offset and gain error vs. full scale.
Note 6: Noise measured with AIN_+ = AIN_- = AGND.
Note 7: Relative accuracy is defined as the difference between the actual RMS amplitude and the ideal RMS amplitude of a 62.5Hz
sine wave, measured over one cycle at a 16ksps data rate, expressed as a fraction of the ideal RMS amplitude. The rela-
tive accuracy specification refers to the maximum error expected over 1 million measurements. Calculated from SNR. Not
production tested.
Note 8: Latency is a function of the sampling rate and XIN clock.
Note 9: Voltage levels below the positive fault threshold and above the negative fault threshold, relative to AGND on each individ-
ual AIN_+ and AIN_- input, do not trigger the analog input protection circuitry.
Note 10: Test performed using RXD MP35.
Note 11: All digital inputs at DGND or DVDD.
Note 12: SYNC is captured by the subsequent XIN clock if this specification is violated.
Note 13: Delay from DVDD exceeds 2.0V until digital interface is operational.
ELECTRICAL CHARACTERISTICS (continued)
(VAVDD = +3.0V to +3.6V, VDVDD = +2.7V to VAVDD, fXIN CLOCK = 24.576MHz, fOUT = 16ksps, VREFIO = +2.5V (external), CREFIO =
CREF0 = CREF1 = CREF2 = CREF3 = 1μF to AGND, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)
