DESCRIPTION
The TS9004 low-voltage, micropower quad analog
comparator is form-factor identical to the MAX934
analog comparator with improved electrical
specifications. Ideal for 3V or 5V single-supply
applications, the TS9004 draws 22% lower supply
current with a 50%-better initial accuracy reference
voltage. The TS9004 joins the TS9001-1/2 and
TS9002 analog comparators in the “NanoWatt
Analog™” high performance analog integrated
circuits portfolio. This quad comparator can operate
from single +2.5V to +11V supplies or from ±1.25V to
±5.5V dual supplies.
The TS9004 exhibits an input voltage range from the
negative supply rail to within 1.3V of the positive
supply. 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 ±1% voltage reference. A GND connection
available at the TS9004’s output stage enables TTL
compatibility and bipolar-to-single ended conversion.
The TS9004 is fully specified over the -40ºC to +85ºC
temperature range and is available in a 16-pin narrow
SOIC package.
