Positive supply.
Voltage output of the D/A converter.
V
OUT
is referenced to V
ZS
.
Zero Scale Voltage. V
OUT
is referenced
to V
ZS
. V
ZS
is normally tied to AGND
in the unipolar mode or to mid-supply
in the bipolar mode. When the device
is operated from a single power
supply, V
ZS
has a maximum current
requirement of –300µA in the bipolar
mode.
Analog ground.
Digital ground. This is the ground
reference level for all digital inputs.
The range is AGND - DGND - V
CC
–
4.5V. DGND is normally tied to
system ground.
Data input — Bit 0 (LSB).
Data input — Bit 1.

Data input — Bit 6.
Data input — Bit 7 (MSB).
Transfer enable input. The data is
transferred into the transparent latch at
the high level of XFER.
Digital gain setting input 0.
Digital gain setting input 1.
Voltage reference output. V
REF OUT
is
referenced to AGND. V
REF OUT
is set
to 2.5V and 5.0V in a low-voltage and
high-voltage operation, respectively
for the ML2350; 2.25V and 4.5V for
the ML2340.
Voltage reference input. V
REF IN
is
referenced to AGND.
