DESCRIPTION…
The HS7541Ais a low–cost, high stability monolithic 12–bit CMOS 4–quadrant multiplying DAC.
It is constructed using a proprietary low–TCR thin–film process that requires no laser–trimming
to achieve 12–bit performance. The HS7541A is a superior pin–compatible replacement for the
industry standard 7541 and AD7541A. It is available in both commercial and industrial
temperature ranges. It operates with +5V to +15V power supply voltages. It is available in 18–
pin plastic DIP and SOIC, and 20–pin PLCC packages.
