1.
Applies only to differential channels.
2.
Variable gain is controlled by setting the PRE_GAIN bits in the ADC_ACR1-8 registers to select a gain factor of
1, 2, or
4. Settings are for differential input only. Tested at 1 gain. Values for other settings are guaranteed by as indicated.
3.
At VRH – VRL = 5.12 V, one LSB = 1.25 mV.
4.
Guaranteed 10-bit mono tonicity.
5.
Voltages between VRL and VRH will not cause damage to the pins. However, they may not be converted accurately if the
differential voltage is above the maximum differential voltage. In addition, conversion errors may occur if the common
mode voltage of the differential signal violates the Differential Input common mode voltage specification.
