Key Features
- Flexible Digital Interface: Data can be loaded in serial mode or as two 8-bit bytes. The serial mode input format is pin selectable to be MSB or LSB first, and the serial output pin allows daisy-chaining of multiple DACs.
- On-Chip Voltage Reference: The internal buried Zener reference is laser trimmed to 10.000 V with a ±0.1% maximum error and a temperature drift performance of ±15 ppm/°C.
- Double-Buffered Latches: Eliminates data skew errors and allows simultaneous updating of DACs in multiDAC systems.
- Output Amplifier: Provides a voltage output settling time of 10 μs to within ½ LSB for a full-scale step and within 2.5 μs for a 1 LSB step over temperature.
- Clear Function: Asynchronously sets the output to 0 V regardless of whether the DAC is in unipolar or bipolar mode.
Applications
- Industrial Control Systems: Where precise analog output is required for control and monitoring applications.
- Medical Devices: For applications requiring high accuracy and reliability in analog output, such as in medical imaging and diagnostic equipment.
- Aerospace and Defense: The AD660ARZ, especially the SQ version compliant to MIL-STD-883, is suitable for military and aerospace applications where high reliability and precision are critical.
- Automotive Systems: For use in automotive control systems that require accurate and reliable analog output.
