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 µs 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 (0000H) or mid-scale (8000H) 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.
