Low power analog comparators from Touchstone Semiconductor

Touchstone Semiconductor has announced the TS9002 dual and the TS9004 quad low power analog comparators plus 1.182-V reference integrated circuits.

As an improved, pin-for-pin functional equivalent to the MAX923, the TS9002s 3.2-A supply current is 16% lower and its 0.75% initial accuracy voltage reference is 25% lower in both specifications compared to the MAX923. As an improved, pin-for-pin functional equivalent to the MAX934, the TS9004s 4.1-A supply current is 25% lower and its 1% initial accuracy reference is 50% lower in both specifications compared to the MAX934.

Ideal for 3V or 5V single-supply applications, the TS9002 dual and the TS9004 quad comparator can operate from single +2.5V to +11V supplies or from 1.25V to 5V dual supplies. Other common features include: a) an input voltage range from the negative supply rail to within 1.3V of the positive supply; b) 7-s propagation delay; c) a push-pull output stage with 40mA source-current drive capability; and d) crowbar-current free output stage switching.

Both comparators are designed for low-voltage, low-power applications, including threshold detectors/discriminators, oscillator circuits, window comparators, level translators, and other battery-powered systems.



TS9002 Dual Comparator Key Specifications

Priced at $0.75 in 1000-piece quantities - $2.10 Less Expensive than MAX923

16% Lower Supply Current: 3.2A vs 4.1A

25% Lower VREF Initial Accuracy: 0.75% vs 1%

User-adjustable Hysteresis via External HYST Pin



TS9004 Quad Comparator Key Specifications

Priced at $1.15 in 1000-piece quantities - $0.60 Less Expensive than MAX934

25% Lower Supply Current: 4.1A vs 5.5A

50% Lower VREF Initial Accuracy: 1% vs 2%

Separate GND Pin for Output Drivers

Both parts are fully specified over the -40C to +85C temperature range. The TS9002 is available in an 8-pin MSOP package and the TS9004 is available in a narrow 16-pin SOIC package. Both products are in stock and ready to ship from Digi-Key, Touchstones authorized distributor.
