TS9002 Dual Comparator and Voltage Reference IC

Touchstone Semiconductor introduces two new low-power, low-voltage comparators with voltage reference for power-sensitive applications.

Milpitas, Calif. (PRWEB) January 07, 2013

Touchstone Semiconductor, a developer of high-performance, low power analog integrated circuit solutions, today 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. Other common features include: a) an input voltage range from the negative supply rail to within 1.3V of the positive supply; b) 7-µs 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
