PRODUCT DESCRIPTION

The AD565A and AD566A are fast 12-bit digital-to-analog

converters that incorporate the latest advances in analog circuit

design to achieve high speeds at low cost.

The AD565A and AD566A use 12 precision, high speed bipolar

current-steering switches, a control amplifier, and a laser-trimmed

thin-film resistor network to produce a very fast, high accuracy

analog output current. The AD565A also includes a buried

Zener reference that features low noise, long-term stability, and

temperature drift characteristics comparable to the best discrete

reference diodes.

The combination of performance and flexibility in the AD565A and

AD566A has resulted from major innovations in circuit design,

an important new high speed bipolar process, and continuing

advances in laser-wafer-trimming techniques (LWT). The

AD565A and AD566A have a 10%–90% full-scale transition

time less than 35 ns and settle to within ±1/2 LSB in 250 ns max

(350 ns for AD566A). Both are laser-trimmed at the wafer level

to ±1/8 LSB typical linearity and are specified to ±1/4 LSB max

error (K and T grades) at +25°C. High speed and accuracy make

the AD565A and AD566A the ideal choice for high speed display

drivers as well as for fast analog-to-digital converters.

The laser trimming process that provides the excellent linearity

is also used to trim both the absolute value and the temperature

coefficient of the reference of the AD565A, resulting in a typical

full-scale gain TC of 10 ppm/°C. When tighter TC performance

is required or when a system reference is available, the AD566A

may be used with an external reference.

AD565A and AD566A are available in four performance

grades. The J

nd K grades are specified for use over the 0°C to

+70°C temperature range while the S and T grades are speci-

fied for the –55°C to +125°C range. The D grades are all pack-

aged in a 24-lead, hermetically sealed, ceramic, dual-in-line

package. The JR grade is packaged in a 28-lead plastic SOIC.

PRODUCT HIGHLIGHTS

1. The wide output compliance range of the AD565A and

AD566A are ideally suited for fast, low noise, accurate voltage

output configurations without an output amplifier.

2. The devices incorporate a newly developed, fully differential,

nonsaturating precision current switching cell structure that

combines the dc accuracy and stability first developed in the

AD562/AD563 with very fast switching times and an optimally

damped settling characteristic.

3. The devices also contain SiCr thin-film application resistors

that can be used with an external op amp to provide a preci-

sion voltage output or as input resistors for a successive-

approximation A/D converter. The 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.

4. The AD565A and AD566A are available in versions compliant

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

Products Databook or current /883B data sheet for detailed

specifications.

NOTES

The digital inputs are guaranteed but not tested over the operating temperature range.

The power supply gain sensitivity is tested in reference to a V

, V

of ± 15 V dc.

For operation at elevated temperatures, the reference cannot supply current for external loads. It, therefore, should be buffered if additional loads are to be supplied.
