The DAC7742 is a 16-bit Digital-to-Analog Converter (DAC)
that provides 16 bits of monotonic performance over the
specified operating temperature range and offers a +10V,
low-drift internal reference. Designed for automatic test equipment
and industrial process control applications, the DAC7742
output swing can be configured in a ±10V, ±5V, or +10V
range. The flexibility of the output configuration allows the
DAC7742 to provide both unipolar and bipolar operation by
pin strapping. The DAC7742 includes a high-speed output
amplifier with a maximum settling time of 5μs to ±0.003%
FSR for a 20V full-scale change and only consumes 100mW
(typical) of power.
The DAC7742 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 (FFFFH) or mid-scale
(7FFFH) overriding the DAC register values. The DAC7742 is
available in an LQFP-48 package and three performance
grades specified to operate from –40°C to +85°C.
