Low-Cost, 7ns, Low-Power
Voltage Comparators
General Description
____________________________Features
ꢀ Fast 7ns Propagation Delay
The MAX9201/MAX9202/MAX9203 high-speed, low-
power, quad/dual/single comparators feature TTL logic
outputs with active internal pullups. Fast propagation
delay (7ns typ at 5mV overdrive) makes these devices
ideal for fast A/D converters and sampling circuits, line
receivers, V/F converters, and many other data-discrim-
ination, signal restoration applications.
ꢀ Low 9mW/Comparator Power Consumption
ꢀ Separate Analog and Digital Supplies
ꢀ Flexible Analog Supply: +5V to +10V or 5V
ꢀ Input Voltage Range Includes
All comparators can be powered from separate analog
and digital power supplies or from a single combined
supply voltage. The analog input common-mode range
includes the negative rail, allowing ground sensing
when powered from a single supply. The MAX9201/
MAX9202/MAX9203 consume only 9mW per compara-
tor when powered from a +5V supply.
Negative Supply Rail
ꢀ TTL-Compatible Outputs
ꢀ TTL-Compatible Latch Inputs
(MAX9202/MAX9203)
ꢀ Available in Space-Saving Packages
8-Pin SOT23 (MAX9203)
The MAX9202/MAX9203 feature output latches with TTL
compatible inputs. The comparator output states are
held when the latch inputs are driven low. The
MAX9201 provides all the same features as the
MAX9202/MAX9203 with the exception of the latches.
14-Pin TSSOP (MAX9202)
16-Pin TSSOP (MAX9201)
The MAX9201/MAX9202/MAX9203 are lower power and
lower cost upgrades to the MAX901/MAX902/MAX903
offering a 50% power savings and smaller packaging.
