The DAC7615 is a quad, serial input, 12-bit, voltage
output digital-to-analog converter (DAC) with guar-
anteed 12-bit monotonic performance over the –40°C
to +85°C temperature range. An asynchronous reset
clears all registers to either mid-scale (800
H
) or zero-
scale (000
H
), selectable via the RESETSEL pin. The
individual DAC inputs are double buffered to allow
GND
for simultaneous update of all DAC outputs. The
device can be powered from a single +5V supply or
from dual +5V and –5V supplies.
Low power and small size makes the DAC7615 ideal
for automatic test equipment, DAC-per-pin program-
mers, data acquisition systems, and closed-loop servo-
control. The device is available in 16-pin plastic DIP,
16-lead SOIC, and 20-lead SSOP packages and is
guaranteed over the –40°C to +85°C temperature range.

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.

All DAC registers become transparent when
LOADDACS is LOW. They are in the latched state
when LOADDACS is HIGH.
The selected input register becomes transparent
when LOADREG is LOW. It is in the latched state
when LOADREG is HIGH.
Asynchronous Reset Input. Sets DAC and input
registers to either zero-scale (000
H
) or mid-scale
(800
H
) when LOW. RESETSEL determines which
code is active.
When LOW, a LOW on RESET will cause the DAC
and input registers to be set to code 000
H
. When
RESETSEL is HIGH, a LOW on RESET will set the
registers to code 800
H
.
