PIN DESCRIPTIONS
Pin Name Description
20 V
DD
Positive supply. Nominal value
+5 volts, ±5%.
1-9 DB0-DB11 Twelve Binary Data Bit inputs. DB11
17-19 is the MSB and DB0 is the LSB.
16
CE Chip Enable. Active low input.
15
CLR Active low digital input that clears the
DAC register to zero, setting the DAC
to minimum scale.
8 DGND Digital ground for input logic.
12 AGND Analog Ground. Ground reference for
the internal bandgap reference voltage,
the DAC, and the output buffer.
13 V
OUT
Voltage output from the DAC. Fixed
output voltage range of 0 V to 4.095 V
with 1 mV/LSB. An internal tempera-
ture stabilized reference maintains a
fixed full-scale voltage independent of
time, temperature and power supply
variations.
14 REFOUT Nominal 2.5 V reference output volt-
age. This node must be buffered if re-
quired to drive external loads.
11 NC No Connection. Leave pin floating.
