GENERAL DESCRIPTION
The MP7543 is a precision, 12-bit CMOS 4-quadrant multi-
plying Digital-to-Analog Converter designed for serial interface
applications.
The MP7543 consists of two 12-bit registers, control logic and
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.
Register B is a 12-bit parallel-in parallel-out register that follows
register A. The contents of register A are loaded into register B
under control of the Load inputs.
A CLEAR input is provided for the asynchronous resetting of
register B to all 0’s.
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.
The MP7543 reduces the additional linearity errors due to
output amplifier offset to only 330
μ
V per millivolt of offset - half
the value of a standard R-2R CMOS DAC design approach.
