Description
1 to 8
D7 to D0
Digital Input Data Bits[D7: D0]. The signal level must be ≤ VDD + 0.3 V.
9
ROFS
Bipolar Offset Resistor. Accepts up to ±18 V. In two-quadrant mode, ties to RFB. In four-quadrant mode, ties to R1
and the external reference.
10
RFB
Internal Matching Feedback Resistor. Connects to the output of an external op amp for I-V conversion.
11
R1
Four-Quadrant Resistor R1. In two-quadrant mode, shorts to the REF pin. In four-quadrant mode, ties to ROFS.
12
RCOM
Center Tap Point of Two Four-Quadrant Resistors, R1 and R2. In four-quadrant mode, ties to the inverting node of
the reference amplifier. In two-quadrant mode, shorts to the REF pin.
13
REF
DAC Reference Input in Two-Quadrant Mode and R2 Terminal in Four-Quadrant Mode. In two-quadrant mode, this
pin is the reference input with constant input resistance vs. code. In four-quadrant mode, this pin is driven by the
external reference amplifier.
14
IOUT
DAC Current Output. Connects to the inverting node of an external op amp for I-V conversion.
15
LDAC
Digital Input Load DAC Control. Signal level must be ≤ VDD + 0.3 V.
16
WR
Write Control Digital Input in Active Low. Transfers shift-register data to the DAC register on the rising edge. The
signal level must be ≤ VDD + 0.3 V.
17
MSB
Power-On Reset State. MSB = 0 resets at zero scale; MSB = 1 resets at midscale. The signal level must be
≤ VDD + 0.3 V.
18
RS
Reset in Active Low. Resets to zero scale if MSB = 0, and resets to midscale if MSB = 1. The signal level must be
≤ VDD + 0.3 V.
19
GND
Analog and Digital Grounds.
20 to 21
D15 to D14
Digital Input Data Bits[D15:D14]. The signal level must be ≤ VDD + 0.3 V.
22 to 27
D13 to D8
Digital Input Data Bits[D13:D8]. The signal level must be ≤ VDD + 0.3 V.
28
VDD
Positive Power Supply Input. Specified range of operation: 2.7 V to 5.5 V.

Description
1 to 6
D5 to D0
Digital Input Data Bits[D5:D0]. The signal level must be
≤ VDD+0.3 V.
7 to 8
NC
No Connection. The user should not connect anything other than dummy pads on these terminals.
9
ROFS
Bipolar Offset Resistor. Accepts up to ±18 V. In two-quadrant mode, ties to RFB. In four-quadrant mode, ties to R1
and the external reference.
10
RFB
Internal Matching Feedback Resistor. Connects to the output of an external op amp for I-V conversion.
11
R1
Four-Quadrant Resistor R1. In two-quadrant mode, shorts to the REF pin. In four-quadrant mode, ties to ROFS.
12
RCOM
Center Tap Point of Two Four-Quadrant Resistors, R1 and R2. In four-quadrant mode, ties to the inverting node of
the reference amplifier. In two-quadrant mode, shorts to the REF pin.
