The AD1139J is one member of the AD1139 family which is designed as the first DAC offering 18-bit resolution (1 part in 262,144) and true 18-bit accuracy in a component size hybrid package. This deivce can be used in (1)sutomatic test equipment;(2)scientific instrumentation;(3)beam positioners;(4)digital audio. And this device is a complete DAC with precision internal reference, latched data inputs and a quality output voltage amplifier.

Features of the AD1139J are:(1)18-bit resolution;(2)low nonlinearity: differential is +/- 1/2 LSB max;(3)integral: +/- 1/2 LSB max;(4)differential TC: +/- 1 ppm/℃ max;(5)integral TC: +/- 1/2 ppm/℃ max;(6)small hermetic 32-lead triple DIP package;(7)low cost;(8)gain TC (with reference): +/- 4 ppm/℃ max.

The absolute maximum ratings of the AD1139J can be summarized as:(1)differential nonlinearity: +/- 1 LSB max;(2)intrgral nonlinearity: +/- 1 LSB max;(3)differential nonlinearity: +/- 1 max.
