1 CHANNEL 8-BIT D/A CONVERTER
The Fujitsu MB4072 is a High-Speed Digital to Analog Converter IC. The
MB4072’s current outputs are high impedance open-collector, which provide
voltage output w ith a load or current t o voltage conv erter for various applications
with operational amplifiers, microcomputers, etc.
Threshold level of digital inputs is variable with the level control input for various
interface level.
