PRODUCT DESCRIPTION

The AD568 is an ultrahigh-speed, 12-bit digital-to-analog con-

verter (DAC) settling to 0.025% in 35 ns. The monolithic de-

vice is fabricated using Analog Devices’ Complementary Bipolar

(CB) Process. This is a proprietary process featuring high-speed

NPN and PNP devices on the same chip without the use of di-

electric isolation or multichip hybrid techniques. The high speed

of the AD568 is maintained by keeping impedance levels low

enough to minimize the effects of parasitic circuit capacitances.

The DAC consists of 16 current sources configured to deliver a

10.24 mA full-scale current. Multiple matched current sources

and thin-film ladder techniques are combined to produce bit

weighting. The DAC’s output is a 10.24 mA full scale (FS) for

current output applications or a 1.024 V FS unbuffered voltage

output. Additionally, a 10.24 V FS buffered output may be gen-

erated using an onboard 1 k span resistor with an external op

amp. Bipolar ranges are accomplished by pin strapping.

Laser wafer trimming insures full 12-bit linearity. All grades of

the AD568 are guaranteed monotonic over their full operating

temperature range. Furthermore, the output resistance of the

DAC is trimmed to 100

cient of the voltage output is 30 ppm/ C max (K).

The AD568 is available in three performance grades. The

AD568JQ and KQ are available in 24-pin cerdip (0.3") packages

and are specified for operation from 0 C to +70 C. The

AD568SQ features operation from –55 C to +125 C and is also

packaged in the hermetic 0.3" cerdip.
