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 Touchstone Semiconductor’s first

analog comparator products in its “NanoWatt Analog”

high-performance analog integrated circuits portfolio.

The TS9001-1/2 draw 600nA of supply current and

include 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-push 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.
