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.
