Product Information

a FEATURES Four Complete Voltage Output DACs Data Register Readback Feature “Reset to Zero” Override Multiplying Operation Double-Buffered Latches Surface Mount and DIP Packages MIL-STD-883 Compliant Versions Available APPLICATIONS Automatic Test Equipment Robotics Process Control Disk Drives Instrumentation Avionics PRODUCT DESCRIPTION Monolithic 12-Bit Quad DAC AD664 PIN CONFIGURATIONS 44-Pin Package The AD664 is four complete 12-bit, voltage-output DACs on one monolithic IC chip. 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 I/O port accommodates 4-, 8- or 12-bit parallel words allowing simple interfacing with a wide variety of microprocessors. A reset to zero control pin is provided to allow a user to simultaneously reset all DAC outputs to zero, regardless of the contents of the input latch. Any one or all of the DACs may be placed in a transparent mode allowing immediate response by the outputs to the input data. The analog portion of the AD664 consists of four DAC cells, four output amplifiers, a control amplifier and switches. Each DAC cell is an inverting R-2R type. The output current from each DAC is switched to the on-board application resistors and output amplifier. The output range of each DAC cell is programmed through the digital I/O port and may be set to unipolar or bipolar range, with a gain of one or two times the reference voltage. All DACs are operated from a single external reference. The functional completeness of the AD664 results from the combination of Analog Devices’ BiMOS II process, laser-trimmed thin-film resistors and double-level metal interconnects. PRODUCT HIGHLIGHTS 28-Pin DIP Package 4. The asynchronous RESET control returns all D/A outputs to zero volts. 5. DAC-to-DAC matching performance is specified and tested. 6. Linearity error is specified to be 1/2 LSB at room temperature and 3/4 LSB maximum for the K, B and T grades. 7. DAC performance is guaranteed to be monotonic over the full operating temperature range. 8. Readback buffers have tristate outputs. 9. Multiplying-mode operation allows use with fixed or variable, positive or negative external references. 10. The AD664 is available in versions compliant with MILSTD-883. Refer to the Analog Devices Military Products Databook or current AD664/883B data sheet for detailed specifications. 1. The AD664 provides four voltage-output DACs on one chip offering the highest density 12-bit D/A function available. 2. The output range of each DAC is fully and independently programmable. 3. Readback capability allows verification of contents of the internal data registers. REV. C Information furnished by Analog Devices is believed to be accurate and reliable.
