The Fujitsu MB4072 is a high-speed digital-to-analog converter IC. The
MB4072 current outputs are high impedance open-collector that provide volt-
age output with a load, or current-to-voltage converter for various applica-
tions with operational amplifiers, microcomputers, etc.
The threshold level of digital inputs is variable with the level control input for
various interface levels.
•Settling time: 85 ns
•Linearity error: .0.19% maximum
•Full-scale temperature coefficient: 10 ppm/C typical
•Output voltage compliance: –10V to +18V
•Multiplying operation
•True/complimentary current sink output
•Adjustable threshold level of digital inputs; interface directly
with TTL, CMOS, ECL, etc.
•Wide supply voltage range: 4.5V to 18V
•Low power consumption: .33 mW at 5V typical
•Operation temperature: -40C to +85C
•Compatible with DAC-08
•Packaging: Plastic DIP package (suffix: –P)
Plastic FPT package (suffix: –PF)

Note :Permanent device damage may occur if the above Absolute Maximum Ratings are exceeded. Functional
operation should be restricted to the conditions as detailed in the operational sections data sheet. Exposure
to absolute maximum rating conditions for extended periods may affect device reliability.
This device contains circuitry to protect the inputs against dam-
age due to high static voltages or electric fields. However, it is
advised that normal precautions be taken to avoid application of
any voltage higher than maximum rated voltages to this high
impedance circuit.
