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 and the TS9004 analog comparators in the “NanoWatt Analog™” high performance analog integrated circuits portfolio. This dual comparator can operate from single +2.5V to +11V supplies or from ±1.25V to ±5V dual supplies.

The TS9002 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. 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.
