DAC7541A
Low Cost 12-Bit CMOS
Four-Quadrant Multiplying
DIGITAL-TO-ANALOG CONVERTER
FEATURES
DESCRIPTION
● FULL FOUR-QUADRANT
The Burr-Brown DAC7541A is a low cost 12-bit,
four-quadrant multiplying digital-to-analog converter.
Laser-trimmed thin-film resistors on a monolithic
CMOS circuit provide true 12-bit integral and differ-
ential linearity over the full specified temperature
range.
MULTIPLICATION
● 12-BIT END-POINT LINEARITY
● DIFFERENTIAL LINEARITY ±1/2LSB MAX
OVER TEMPERATURE
● MONOTONICITY GUARANTEED OVER
DAC7541A is a direct, improved pin-for-pin replace-
ment for 7521, 7541, and 7541A industry standard
parts. In addition to a standard 18-pin plastic package,
the DAC7541A is also available in a surface-mount
plastic 18-pin SOIC.
TEMPERATURE
● TTL-/CMOS-COMPATIBLE
● SINGLE +5V TO +15V SUPPLY
● LATCH-UP RESISTANT
● 7521/7541/7541A REPLACEMENT
● PACKAGES: Plastic DIP, Plastic SOIC
● LOW COST
