DESCRIPTION

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.
