NAME

PIN DESCRIPTION

D0(LSB) thru Digital Data Bit 0, the Least Significant Bit thru Digital Data Bit 7, the Most Significant Bit.

D7(MSB)

BLNK

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

when Low.

DVSS

VB

CLK

Digital Ground.

Voltage Bias, connect a 0.1µF capacitor to DVSS.

Data Clock Pin 100kHz to 40MHz.

AVSS

IREF

VREF

Analog Ground.

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

than the resistor on IOUT1. (See Typical Applications Circuit).

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