DESCRIPTION
The nanopower TS9001-1/2 analog comparators
guarantee +1.6V operation, draw very little supply
current, and have robust input stages that can
tolerate input voltages beyond the power supply. Both
products are the first analog comparator products in
the “NanoWatt Analog” high-performance analog
integrated circuits portfolio. The TS9001-1/2 draws
600nA of supply current and includes an on-board
+1.252V±1% reference. These comparators are also
electrically and form-factor identical to the MAX9117
and the MAX9118 family of analog comparators. Both
comparators offer a 33% improvement in voltage
reference initial accuracy and the TS9001-1 offers
73% higher output current drive.
The TS9001-1’s push-pull output drivers were
designed to drive 5mA loads from one supply rail to
the other supply rail. The TS9001-2’s open-drain
output stage make it easy to incorporate this analog
comparator into systems that operate on different
supply voltages. Both devices are available in an
ultra-small 5-pin SC70 package.
