High-Speed, Low-Power Voltage Comparators
General Description
The MAX900–MAX903 high-speed, low-power, single/
dual/quad voltage comparators feature differential ana-
log inputs and TTL-logic outputs with active internal pull-
ups. Fast propagation delay (8ns typ at 5mV overdrive)
makes the MAX900–MAX903 ideal for fast A/D convert-
ers and sampling circuits, line receivers, V/F converters,
and many other data-discrimination applications.
All comparators can be powered from separate analog
and digital power supplies or from a single combined sup-
ply voltage. The analog input common-mode range
includes the negative rail, allowing ground sensing when
powered from a single supply. The MAX900–MAX903
consume 18mW per comparator when powered from +5V.
The MAX900–MAX903 are equipped with independent
TTL-compatible latch inputs. The comparator output
states are held when the latch inputs are driven low. The
MAX901 provides the same performance as the
MAX900/MAX902/MAX903 with the exception of the
latches.
For newer, pin-for-pin compatible parts with the same
speed and only half the power dissipation, see the
MAX9201/MAX9202/MAX9203 data sheet.
