PRODUCT DESCRIPTION

The AD667 is available in five performance grades. The

The AD667 is a complete voltage output 12-bit digital-to-analog

converter including a high stability buried Zener voltage refer-

ence and double-buffered input latch on a single chip. The

converter uses 12 precision high speed bipolar current steering

switches and a laser trimmed thin-film resistor network to pro-

vide fast settling time and high accuracy.

AD667J and K are specified for use over the 0°C to +70°C tem-

perature range and are available in a 28-pin molded plastic DIP

(N) or PLCC (P) package. The AD667S grade is specified for

the –55°C to +125°C range and is available in the ceramic DIP

(D) or LCC (E) package. The AD667A and B are specified for

use over the –25°C to +85°C temperature range and are avail-

able in a 28-pin hermetically sealed ceramic DIP (D) package.

Microprocessor compatibility is achieved by the on-chip double-

buffered latch. The design of the input latch allows direct inter-

face to 4-, 8-, 12-, or 16-bit buses. The 12 bits of data from the

first rank of latches can then be transferred to the second rank,

avoiding generation of spurious analog output values. The latch

responds to strobe pulses as short as 100 ns, allowing use with

the fastest available microprocessors.

PRODUCT HIGHLIGHTS

1. The AD667 is a complete voltage output DAC with voltage

reference and digital latches on a single IC chip.

2. The double-buffered latch structure permits direct interface

to 4-, 8-, 12-, or 16-bit data buses. All logic inputs are TTL

or 5 volt CMOS compatible.

The functional completeness and high performance in the

AD667 results from a combination of advanced switch design,

high speed bipolar manufacturing process, and the proven laser

wafer-trimming (LWT) technology. The AD667 is trimmed at

the wafer level and is specified to ±1/4 LSB maximum linearity

error (K, B grades) at +25°C and ±1/2 LSB over the full operat-

ing temperature range.

3. The internal buried Zener reference is laser-trimmed to 10.00

volts with a ±1% maximum error. The reference voltage is

also available for external application.

4. The gain setting and bipolar offset resistors are matched to

the internal ladder network to guarantee a low gain tempera-

ture coefficient and are laser-trimmed for minimum full-scale

and bipolar offset errors.

The subsurface (buried) Zener diode on the chip provides a low

noise voltage reference which has long-term stability and tem-

perature drift characteristics comparable to the best discrete ref-

erence diodes. The laser trimming process which provides the

excellent linearity, is also used to trim the absolute value of the

reference as well as its temperature coefficient. The AD667 is

thus well suited for wide temperature range performance with

±1/2 LSB maximum linearity error and guaranteed monotonic-

ity over the full temperature range. Typical full-scale gain TC is

5 ppm/°C.

5. The precision high speed current steering switch and on-board

high speed output amplifier settle within 1/2 LSB for a 10 V

full-scale transition in 2.0 µs as when properly compensated.

6. The AD667 is available in versions compliant with MIL-

STD-883. Refer to the Analog Devices Military Products

Databook or current AD667/883B data sheet for detailed

specifications.
