DAC7741 说明

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 equipment 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 5us 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.
