PIN DESCRIPTION

Digital Data Bit 0, the Least Significant Bit thru Digital Data Bit 7, the Most Significant Bit.

Blanking Line, used to clear the internal data register to the zero condition when High, normal operation when Low.

Digital Ground.

Voltage Bias, connect a 0.1F capacitor to DVSS.

Data Clock Pin 100kHz to 40MHz.

Analog Ground.

Current Reference, used to set the current range. Connect a resistor to AVSS that is 16 times greater than the re-

sistor on IOUT1. (See Typical Applications Circuit).

Input Reference Voltage used to set the output full scale range.

Voltage Ground, connect a 0.1F capacitor to AVDD.

Analog Supply 4.75V to 7V.

Current Output Pin.
