AD7244
FUNCTIONAL BLOCK DIAGRAM AD7242isobsolete GENERAL DESCRIPTION The AD7242/AD7244 is a fast, complete, dual 12-bit/14-bit
voltage output D/A converter. It consists of a 12-bit/14-bit
DAC, 3 V buried Zener reference, DAC output amplifiers and
high speed serial interface logic.
Interfacing to both DACs is serial, minimizing pin count and
allowing a small package size. Standard control signals allow
interfacing to most DSP processors and microcontrollers.
Asynchronous control of DAC updating for both DACs is made …
