Most significant data bit of digital input word.
Eight bits of 10-bit digital input word.
Least significant data bit of digital input word.
TTL-compatible edge-triggered latch enable signal for on-board registers.
No internal connection to this pin.
+5 V supply voltage for digital circuitry.
Converter Ground.
–5.2 V supply voltage for digital circuitry.
Connection for external reference set resistor; nominal 1.96 k
. Full-scale output current =
32 (Control Amp in V/R
SET
).
Analog Return. This point and the reference side of the DAC load resistors should be con-
nected to the same potential (nominally ground).
Analog current output; full-scale current occurs with a digital word input of all “1s.” With
external load resistor, output voltage = I

is nominally

.
Complementary analog current output; full-scale current occurs with a digital word input
of all “0s.”
Negative analog supply, nominally –5.2 V.
Normally connected to CONTROL AMP OUT (Pin 24). Direct line to DAC current
source network. Voltage changes (noise) at this point have a direct effect on the full-scale
output current of the DAC. Full-scale current output = 32 (CONTROL AMP IN/R
SET
)
when using the internal amplifier. DAC load is virtual ground.
Normally connected to REF IN (Pin 23). Output of internal control amplifier which pro-
vides a reference for the current switch network.
Normally connected to CONTROL AMP IN (Pin 26). Internal voltage reference, nomi-
nally –1.25 V.
Normally connected to REF Out (Pin 25) if not connected to external reference.
Negative digital supply, nominally –5.2 V.
