Integrated pre-amp, output driver earmark voltage comparators
Keywords:pre-amp output driver? voltage comparator? CMOS?
The ALD2331/ALD2331A/ALD2331B series voltage comparators offer ultralow offset voltages and offset currents. The comparator is built using advanced silicon gate EPAD CMOS technology for high-performance, high-precision analog applications such as low-level signal detection circuits that require low stand-by power and high-output current capability. The EPAD technology also allows ALD to reduce die size and integrate three components in an industry-standard 8-pin SOIC.
The voltage comparator series features a high typical input impedance of 1012?, low input bias current of 10pA and a fast response time of 750ns with only 10mV input step signal. The EPAD voltage comparator also features a low power dissipation of 55?A and single +5V or dual power supply operation.
The input voltage of the device includes ground, making it suitable for low-level signal detection with high source impedance. The outputs are open-drain configurations, allowing maximum application flexibility. These features are well-suited for such applications as high-source-impedance voltage comparison circuits, dual-limit window comparators, power supply voltage monitors, and photo-detector sensor circuits.
The devices are available now at $1.47 in quantities of 1,000.
