DESCRIPTION
The DAC7741 is a 16-bit Digital-to-Analog Converter (DAC)
which provides 16 bits of monotonic performance over the
specified operating temperature range and offers a +10V,
low-drift internal reference. Designed for automatic test equip-
ment and industrial process control applications, the DAC7741
output swing can be configured in a
±
10V,
±
5V, or +10V
range. The flexibility of the output configuration allows the
DAC7741 to provide both unipolar and bipolar operation by
pin strapping. The DAC7741 includes a high-speed output
amplifier with a maximum settling time of 5
μ
s to
±
0.003%
FSR for a 20V full-scale change and only consumes 100mW
(typical) of power.
The DAC7741 features a standard 16-bit parallel interface with
double buffering to allow asynchronous updates of the analog
output and data read-back to support data integrity verification
prior to an update. A user-programmable reset control allows
the DAC output to reset to min-scale (0000
H
) or mid-scale
(8000
H
) overriding the DAC register values. The DAC7741 is
available in a LQFP-48 package and four performance grades
specified to operate from 0
°
C to +70
°
C and
–
40
°
C to +85

C.
