Positive supply. Nominal value
+5 volts,
±
5%.
Twelve Binary Data Bit inputs. DB11
is the MSB and DB0 is the LSB.
Chip Enable. Active low input.
Active low digital input that clears the
DAC register to zero, setting the DAC
to minimum scale.
Digital ground for input logic.
Analog Ground. Ground reference for
the internal bandgap reference voltage,
the DAC, and the output buffer.
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.
Nominal 2.5 V reference output volt-
age. This node must be buffered if re-
quired to drive external loads.
No Connection. Leave pin floating.
SUBSTRATE IS COMMON WITH V
