MAX516BCNG+

The MAX516BCNG+ is a quad, DAC programmed CMOS comparator with programmable threshold in 24 pin DIP package. This device combines four low power comparator on a single CMOS IC, separate 8bit digital to analogue converters (DAC) drive the comparator inverting inputs so that individual trip threshold can be digitally set. All non-inverting comparator inputs are brought out as analogue inputs (AIN0 to AIN3). Each comparator output swings high when its analogue inputs exceed its digitally set threshold. All four DACs share a common reference input to optimize matching and eliminate external trims. Digital inputs and comparator outputs are compatible with TTL and CMOS logic. A separate logic supply (VCC) allows comparator output levels to be set independently of VDD. The MAX516B operates from single supply with VDD tied to VCC. It is used in window comparator, power supply monitors, alarm limit detectors, battery chargers and automated test equipment.
