Touchstone Semiconductor Introduces Two New Low-Power, Low-Voltage Comparators for Power-Sensitive Applications

Touchstone Semiconductor TS9002 TS9004

The New TS9002 Dual is $2.10 Less Expensive than MAX923 and the New TS9004 Quad Is $0.60 Less Expensive than MAX934.

Touchstone Semiconductor 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 TS9002’s 3.2-μA 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 TS9004’s 4.1-μA 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.

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.
