Quad Comparator with Programmable Threshold

The MAX516 combines four low-power, programmablethreshold comparators on a single CMOS IC. Separate 8-bit digital-to-analog converters (DACs) drive the comparator inverting (-) inputs so that individual trip thresholds can be digitally set. All noninverting (+)comparator inputs are brought out as analog inputs (AIN0- AIN3). Each comparator output swings high when its analog input exceeds 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 MAX516 operates conveniently from a single supply with VDD tied to (VCC). Commercial, extended, and military temperature ranges are provided in 24-pin narrow DIP and wide SO packages.
