A.7.11 Inter-channel Gain Mismatch
* Identical channel configurations.
** Operating temperature within 5 °C of last auto-calibration temperature.
A.7.12 Inter-channel Phase Mismatch
* Identical channel configurations.
** Operating temperature within 5 °C of last auto-calibration temperature.
A.8 Integrated Electronic Piezoelectric Excitation
(IEPE)
 Current: 0, 4, or 10 mA ± 5%, each channel independently software selectable
 Compliance: 24 V min
 Channel input impedance with IEPE enabled: 200 k Ω @ 1 kHz, pseudo-dif-
ferential
A.9 Reference Clock Characteristics
 Using external reference clock (25 MHz):
– Accuracy: Equal to accuracy of external reference clock
 Using internal reference clock:
– Accuracy: ±20 ppm, over operating temperature range, in first year
– Aging: 3 ppm/year
