3.1.5 Power-down Control

The device has two power-down modes to conserve power. If the chip is put in stand-by mode all circuitry except

the clock generator is turned off.

S1,S0

Power-down mode

00 = Reserved

01 = Halt and enter stand-by power saving mode. This mode allows quick power-on time

10 = Halt and enter sleep power saving mode. This mode requires a slow power-on time

11 = Reserved

3.1.6 Calibration Control

The device has the capability of performing a system offset and gain calibration. The user must supply the prop-

er inputs to the device before proceeding with the calibration cycle.

Cv,Ci

Designates calibration channel

00 = Not allowed

01 = Calibrate the current channel

10 = Calibrate the voltage channel

11 = Calibrate voltage and current channel simultaneously

GC

Designates gain calibration

0 = Normal operation

1 = Perform gain calibration

OC

Designates offset calibration

0 = Normal operation

1 = Perform offset calibration
