Offset error is the deviation of the average code from mid-code for a zero input. Offset error is expressed in terms of % of full-scale.
Fixed attenuation in the channel arises due to a fixed attenuation of about 1% in the sample-and-hold amplifier. When the differential
voltage at the analog input pins are changed from -V
REF
to +V
REF
, the swing of the output code is expected to deviate from the full-scale
code (4096LSB) by the extent of this fixed attenuation.
NOTE: V
is defined as (REF
- REF
).
Variable attenuation in the channel refers to the attenuation of the signal in the channel over and above the fixed attenuation.
The reference voltages are trimmed at production so that (VREF
T
- VREF
B
) is within
±
50mV of the ideal value of 1V. It does not include
fixed attenuation.
The attenuation temperature coefficient refers to the temperature coefficient of the attenuation in the channel. It does not account for the
variation of the reference voltages with temperature.
V
provides the common-mode current for the inputs of all four channels when the inputs are AC-coupled. The V
CM
output current
specified is the additional drive of the V
buffer if loaded externally.
Average current drawn from the reference pins in the external reference mode.
