PRODUCT DESCRIPTION

PRODUCT HIGHLIGHTS

The AD767 is a complete voltage output 12-bit digital-to-

analog converter including a high stability buried Zener

reference and 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 provide high accuracy.

1. The AD767 is a complete voltage output DAC with voltage

reference and digital latches on a single IC chip.

2. The input latch responds to write pulse widths as short as

40 ns assuring direct interface with the industry’s fastest

microprocessors.

Microprocessor compatibility is achieved by the on-chip latch.

The design of the input latch allows direct interface to 12-bit

buses. The latch responds to strobe pulses as short as 40 ns,

allowing use with the fastest available microprocessors.

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 temperature

coefficient and are laser trimmed for minimum full-scale and

bipolar offset errors.

The functional completeness and high performance of the

AD767 result from a combination of advanced switch design,

high-speed bipolar manufacturing process, and the proven laser

wafer-trimming (LWT) technology.

5. The precision high-speed current steering switches and

on-board high-speed output amplifier settle within 1/2 LSB

for a 10 V full-scale transition in 3.0 µs when properly

compensated.

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

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

temperature drift characteristics comparable to the best discrete

reference 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 AD767 is

thus well suited for wide temperature range performance with

±1/2 LSB maximum linearity error and guaranteed monotonicity

over the full temperature range. Typical full-scale gain T.C. is

5 ppm/°C.

6. The AD767 is available in versions compliant with

MIL-STD-883. Refer to the Analog Devices Military

Products Databook or current AD767/883B data sheet for

detailed specifications.
