Gain Register
The gain register span is from 0 to (4-2-22). After Reset the (MSB-1) bit is ‘1’, all other bits are ‘0’.
The gain calibration results is stored in the gain
register. The result sets the slope of the ADC’s
transfer function. The gain register spans from 0 to
(4 - 2-22). The decimal equivalent meaning of the
gain register is
where the binary numbers have a value of either
zero or one (b0 corresponds to bit MSB-1, N = 22).
Self Calibration
The CS5529 offers both self offset and self gain
calibrations. For the self-calibration of offset, the
converter internally ties the inputs of the modulator
together and routes them to the VREF- pin as
shown in Figure 6. Also self offset calibration re-
quires that VREF- be tied to a fixed voltage be-
tween VA+ and VA-. For self-calibration of gain,
the differential inputs of the modulator are connect-
ed to VREF+ and VREF- as shown in Figure7.
System Calibration
For the system calibration functions, the user must
input signals which represent system ground and
system full scale to the converter. When a system
offset calibration is performed a ground reference
signal must be applied to the converter (see Figure
8). When a system gain calibration is performed,
the user must input a signal representing the posi-
tive full scale point as shown in Figure 9. In either
case, calibration signals must be within the speci-
fied calibration limits for each specific calibration
step (refer to the System Calibration Specifica-
