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 Touchstone’s 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 a 8-pin MSOP
package.
