LTC2751
S1 (Pin 33): Span I/O Bit 1. Pins S0, S1 and S2 are used to
program and to read back the output range of the DAC.
R
±5V. If not used, R
I
negative input of the I/V converter amplifi er.
R
the output of the I/V converter amplifi er. The DAC output
current from I

PIN FUNCTIONS
OUT1
VOS
FB
(Pin 36): DAC Feedback Resistor; normally tied to
(Pin 34): DAC Offset Adjust. Nominal input range is
(Pin 35): DAC current output; normally tied to the
FB
pin.
OUT1
VOS
fl ows through the feedback resistor
should be shorted to I
OUT2
.
R
the translation of the output voltage range for bipolar
spans. Accepts up to ±15V; normally tied to the positive
reference voltage at R
REF (Pin 38): Feedback Resistor for the Reference Inverting
Amplifi er, and Reference Input for the DAC. Normally tied
to the output of the reference inverting amplifi er. Typically
–5V. Accepts up to ±15V.
Exposed Pad (Pin 39): Ground. The Exposed Pad must
be soldered to the PCB.
OFS
(Pin 37): Bipolar Offset Network. This pin provides
IN
(Pin 2).
