The CS5464 can perform system calibrations. Proper input signals must be applied to the current and voltage chan-

nel before performing a designated calibration.

CAL[5:4]*

Designates calibration to be performed

00 = Channel DC offset

01 = Channel DC gain

10 = Channel AC offset

11 = Channel AC gain

CAL[3:0]*

Designates channel to calibrate

0001 = Current channel

0010 = Voltage channel

0100 = Current channel 2

1000 = Voltage channel 2

*By utilizing different combinations for CAL[3:0], multiple channels can be calibrated simultaneously, e.g.

CAL[5:0] = 001111 commands the CS5464 to perform a DC offset calibration on all four channels. Values

for CAL[5:0] not specified should not be used.
