Description

The MAX900–MAX903 high-speed, low-power, single/dual/quad voltage comparators feature differential analoginputs and TTL-logic outputs with active internal pullups.Fast propagation delay (8ns typ at 5mV overdrive)makes the MAX900–MAX903 ideal for fast A/D convertersand sampling circuits, line receivers, V/F converters,and many other data-discrimination applications.All comparators can be powered from separate analogand digital power supplies or from a single combined supplyvoltage. The analog input common-mode rangeincludes the negative rail, allowing ground sensing whenpowered from a single supply. The MAX900–MAX903consume 18mW per comparator when powered from +5V.The MAX900–MAX903 are equipped with independentTTL-compatible latch inputs. The comparator outputstates are held when the latch inputs are driven low. TheMAX901 provides the same performance as theMAX900/MAX902/MAX903 with the exception of thelatches.For newer, pin-for-pin compatible parts with the samespeed and only half the power dissipation, see theMAX9201/MAX9202/MAX9203 data sheet.ApplicationsHigh-Speed A/D ConvertersHigh-Speed Data SamplingHigh-Speed V/F ConvertersInput Trigger CircuitryLine ReceiversPWM CircuitsThreshold Detectors
