The dual (TS9002) and quad (TS9004) devices can operate from single 2.5 to 11V supplies or from ±1.25 to ±5V dual supplies.
Other features include an input voltage range from the negative supply rail to within 1.3V of the positive supply; 7µs propagation delay; a push pull output stage with 40mA source current drive capability; and crowbar current free output stage switching.
As an improved, pin for pin functional equivalent to the MAX923, Touchstone says the TS9002's 3.2µA supply current is 16% lower and its ±0.75% initial accuracy voltage reference is 25% lower in both specifications compared to the MAX923.
In addition, the TS9004's 4.1µA supply current is said to be 25% lower than the MAX934, with its ±1% initial accuracy reference 50% lower in both specifications.
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.
