Product Summary

The AD664BD-UNI is a Monolithic 12-Bit Quad DAC. Each DAC has a double-buffered input latch structure and a data readback function. All DAC read and write operations occur through a single microprocessor-compatible I/O port. The analog portion of the AD664BD-UNI consists of four DAC cells, four output amplifiers, a control amplifier and switches. Each DAC cell is an inverting R-2R type. The applications of the AD664BD-UNI include Automatic Test Equipment, Robotics, Process Control, Disk Drives, Instrumentation, Avionics.
