AD768ARZ

AD768 is a 16bit, high speed digital-to-analogue converter that offers exceptional ac and dc performance. The AD768 is manufactured on ADI’s Advanced Bipolar CMOS (ABCMOS) process, combining the speed of bipolar transistors, the accuracy of laser-trimmable thin film resistors, and the efficiency of CMOS logic. A segmented current source architecture is combined with a proprietary switching technique to reduce glitch energy and maximize dynamic accuracy. Edge triggered input latches and a temperature compensated bandgap reference have been integrated to provide a complete monolithic DAC solution. Differential current outputs are provided to support single-ended or differential applications. The current outputs may be tied directly to an output resistor to provide a voltage output, or fed to the summing junction of a high speed amplifier to provide a buffered voltage output. Application includes arbitrary waveform generation, communications waveform reconstruction, vector stroke display.
