GENERAL DESCRIPTION
The MP7533 is a low cost, 10-bit multiplying Digital-to-Analog
Converter. This device uses EXAR’s patented advanced thin
film resistor and CMOS technologies, providing up to 10-bit accuracies with TTL/CMOS compatibility.
BENEFITS
• Accurate Converter at Low Cost
• Can be used in Reverse Mode (V oltage Out)
• Flexible Design
APPLICATIONS
• Digital/Analog Multiplication
• Character Generation
• Programmable Power Supplies
• Gain Controlled Circuits
Pin and functional equivalent to the industry standard
MP7520, the MP7533 is recommended as a lower cost alternative for old MP7520 sockets or new 10-bit DAC designs.
The MP7533 applications include: digital-to-analog multiplication, CRT character generation, programmable power supplies, digitally controlled gain circuits, etc.

NOTES:
1
Full Scale Range (FSR) is 10V for unipolar mode.
2
Guaranteed but not production tested
3
Digital Input levels should not go below ground or exceed the positive supply voltage, otherwise damage may occur.
4
Specified values guarantee functionality. Refer to other parameters for accuracy.
