Product Summary

The adc912afs is a monolithic 12-bit accurate CMOS A/D converter. It contains a complete successive-approximation A/D converter built with a high-accuracy D/A converter, a precision bipolar transistor high-speed comparator, and successive-approximation logic including three-state bus interface for logic compatibility. The accuracy of the adc912afs results from the addition of precision bipolar transistors to Analog Devices advanced-oxide isolated silicon-gate CMOS process. The applications of the adc912afs are (1)Data Acquisition Systems; (2)DSP System Front End; (3)Process Control Systems; (4)Portable Instrumentation.
