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 and 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.
