The AD568 is an ultrahigh-speed, 12-bit digital-to-analog converter (DAC) settling to 0.025% in 35 ns. The monolithic device 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 dielectric 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 generated using an onboard 1 k(ohm) 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(ohm) =/-1.0%. The gain temperature coefficient 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.
