NOTES
1Temperature ranges as follows: A, B Versions, –40
°C to +85°C; S Version, –55°C to +125°C.
2Specifications apply after calibration.
3Not production tested. Guaranteed by characterization at initial product release.
4Sample tested @ +25
°C to ensure compliance.
5All digital inputs @ DGND except for
CONVST @ DV
DD. No load on the digital outputs. Analog inputs @ AGND.
6CLKIN @ DGND when external clock off. All digital inputs @ DGND except for
CONVST @ DV
DD. No load on the digital outputs. Analog inputs @ AGND.
7The offset and gain calibration spans are defined as the range of offset and gain errors that the AD7854/AD7854L can calibrate. Note also that these are voltage spans
and are not absolute voltages (i.e., the allowable system offset voltage presented at AIN(+) for the system offset error to be adjusted out will be AIN(–)
± 0.05 × V
REF,
and the allowable system full-scale voltage applied between AIN(+) and AIN(–) for the system full-scale voltage error to be adjusted out will be VREF
± 0.025 × V
REF
(unipolar mode) and VREF/2
± 0.025 × V
REF (bipolar mode)). This is explained in more detail in the calibration section of the data sheet.
Specifications subject to change without notice.
