Overview
The AD660ARZ-REEL, produced by Analog Devices Inc., is a complete 16-bit monolithic digital-to-analog converter (DAC) known as the DACPORT. This device integrates an on-board voltage reference, double-buffered latches, and an output amplifier on a single chip. Manufactured using the BiMOS II process, it combines low power CMOS logic with high precision bipolar linear circuitry. The AD660ARZ-REEL is part of the AD660 series, which offers various packaging options, including the 24-lead SOIC (Wide) package for this specific model.

Key Features
- Complete 16-bit DAC Function: Includes an on-board voltage reference, double-buffered latches, and an output amplifier.
- 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.
- Output Range Programmability: The output range can be set to provide a unipolar output range of 0 V to 10 V or a bipolar output range of −10 V to +10 V without external components.
- High Precision: Integral and differential nonlinearity maintained at ±0.003% maximum. The on-chip output amplifier provides a voltage output settling time of 10 μs to within ½ LSB for a full-scale step.
- Microprocessor Compatibility: Supports asynchronous clear to 0 V function and fast (40 ns) write pulse.
- Multiple Packaging Options: Available in 24-lead PDIP, SOIC, and CERDIP packages, with the AR and BR versions specified from −40°C to +85°C.
Applications
- Industrial Control Systems: Suitable for precision control and measurement applications.
- Medical Devices: Used in medical equipment requiring high accuracy and reliability.
