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 Touchstone’s 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 ±0.75% 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.

Electrical and thermal stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These
are stress ratings only and functional operation of the device at these or any other condition beyond those indicated in the operational sections
of the specifications is not implied. Exposure to any absolute maximum rating conditions for extended periods may affect device reliability and
lifetime.
