PRODUCT DESCRIPTION

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.

28-Pin DIP Package

The I/O port accommodates 4-, 8- or 12-bit parallel words al-

lowing simple interfacing with a wide variety of microprocessors.

A reset to zero control pin is provided to allow a user to simulta-

neously 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 pro-

grammed through the digital I/O port and may be set to unipo-

lar or bipolar range, with a gain of one or two times the reference

voltage. All DACs are operated from a single external reference.

4. The asynchronous RESET control returns all D/A outputs

to zero volts.

5. DAC-to-DAC matching performance is specified and tested.

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.

6. Linearity error is specified to be 1/2 LSB at room tempera-

ture 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.

PRODUCT HIGHLIGHTS

1. The AD664 provides four voltage-output DACs on one chip

offering the highest density 12-bit D/A function available.

8. Readback buffers have tristate outputs.

9. Multiplying-mode operation allows use with fixed or vari-

able, positive or negative external references.

2. The output range of each DAC is fully and independently

programmable.

10. The AD664 is available in versions compliant with MIL-

STD-883. Refer to the Analog Devices Military Products

Databook or current AD664/883B data sheet for detailed

specifications.

3. Readback capability allows verification of contents of the in-

ternal data registers.
