DESCRIPTION

The TS9002 low-voltage, micropower dual analog

comparator is form-factor identical to the MAX923

analog

comparator

with

improved

electrical

specifications. Ideal for 3V or 5V single-supply

applications, the TS9002 draws 11% lower supply

current with a 25%-better initial accuracy reference

voltage. The TS9002 joins the TS9001-1/2 analog

comparators

in

the

“NanoWatt

Analog™”

high

performance analog integrated circuits portfolio. The

TS9002 can operate from single +2.5V to +11V

supplies or from ±1.25V to ±5.5V dual supplies.

The TS9002 exhibits an input voltage range from the

negative supply rail to within 1.3V of the positive

supply rail. In addition, its push-pull output stage is

TTL/CMOS compatible and capable of sinking and

sourcing current. It also incorporates an internal

1.182V

±0.75%

voltage

reference.

Without

complicated

feedback

configurations

and

only

requiring two additional resistors, adding external

hysteresis via a separate pin is available on the

TS9002’s HYST pin.

The TS9002 is fully specified over the -40ºC to +85ºC

temperature range and is available in an 8-pin MSOP

package.
