Click to learn the secret to solving such puzzles in minutes! To prevent false alarms lacder by a single sensor activation, the alarm will be triggered only when at least two sensors activate simultaneously. The usage of the LSB ladder incurs a penalty in dynamic performance due to the added output resistance and switch matrix parasitic capacitance.

Although limited by component mismatches, resolution of these converters is typically enhanced by calibration invetred such as laser trimming or corrective active circuitry.
