ELECTRICAL CHARACTERISTICS (continued)
(V
C
Note 1: Devices are production tested at +105°C. Specifications to -40°C are guaranteed by design.
Note 2: Tested at V
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
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
Note 8: Latency is a function of the sampling rate and XIN clock. See the Latency section in the Digital Filter section.
Note 9: Voltage levels below the positive fault threshold and above the negative fault threshold, relative to AGND on each individ-
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.
