pin FuncTions
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
VOS
(Pin 34): DAC Offset Adjust. Nominal input range is
±5V. If not used, R
VOS
should be shorted to I
OUT2
.
I
OUT1
(Pin 35): DAC current output; normally tied to the
negative input of the I/V converter amplifier.
R
FB
(Pin 36): DAC Feedback Resistor; normally tied to
the output of the I/V converter amplifier. The DAC output
current from I
OUT1
flows through the feedback resistor
to the R
FB
pin.
R
OFS
(Pin 37): Bipolar Offset Network. This pin provides
the translation of the output voltage range for bipolar
spans. Accepts up to ±15V; normally tied to the positive
reference voltage at R
IN
(Pin 2).
REF (Pin 38): Feedback Resistor for the Reference Inverting
Amplifier, and Reference Input for the DAC. Normally tied
to the output of the reference inverting amplifier. Typically
–5V. Accepts up to ±15V.
Exposed Pad (Pin 39): Ground. The Exposed Pad must
be soldered to the PCB.
