GENERAL DESCRIPTION

The MP7543 is a precision, 12-bit CMOS 4-quadrant multi-

plying Digital-to-Analog Converter designed for serial interface

applications.

under control of the Load inputs.

A CLEAR input is provided for the asynchronous resetting of

The MP7543 is manufactured using an advanced thin film

monolithic CMOS fabrication process. A unique decoding tech-

nique is utilized yielding excellent accuracy and stability. 12-bit

linearity is achieved without laser trimming.

TheMP7543consistsoftwo12-bitregisters, controllogicand

a 12-bit multiplying D/A converter. The input register (register A)

is a 12-bit serial-in parallel-out shift register. Serial data at the

SR1 pin is clocked into Register A on the leading or trailing edge

(user selected) of the strobe input, with the MSB loaded first.

The MP7543 reduces the additional linearity errors due to

output amplifier offset to only 330 µV per millivolt of offset - half

the value of a standard R-2R CMOS DAC design approach.
