GENERAL DESCRIPTION
The MP7542 is a precision, 12-bit CMOS 4-quadrant multi-
plying Digital-to-Analog Converter designed for direct interface
to 4 and 8-bit microprocessors.
The MP7542 consists of three 4-bit registers, a 12-bit DAC
register, address decoding logic, and a 12-bit CMOS multiplying
DAC. Data is loaded into the data registers in three 4-bit nibbles
and subsequently transferred to the 12-bit DAC register. All data
loading or data transfer operations are identical to the WRITE
cycle of a static RAM. A CLEAR input allows the 12-bit DAC reg-
ister to be reset to all zeros.
The MP7542 is manufactured using advanced thin-film on
monolithic double metal CMOS fabrication process. A unique
decoding technique is utilized yielding excellent accuracy and
stability.
The MP7542 reduces the additional linearity errors due to
output amplifier offset to only 330
μ
V per millivolt of offset versus
670
μ
V for the standard R-2R ladder CMOS DACs.
