MAX9203 Datasheet, PDF (1/8 Pages) Maxim Integrated Products – Low-Cost, 7ns, Low-Power Voltage Comparators

19-1936; Rev 1; 1/05
Low-Cost, 7ns, Low-Power
Voltage Comparators
General Description
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.
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.
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.
The MAX9201/MAX9202/MAX9203 are lower power and
lower cost upgrades to the MAX901/MAX902/MAX903
offering a 50% power savings and smaller packaging.
