Texas Instruments LM2903P Dual Differential Comparator IC, DIP, 8 Pins

The Texas Instruments LM2903P is a dual differential comparator IC designed for reliable performance across a wide range of applications. Featuring two independent comparators, this device operates from a single power supply over a broad voltage range of 2V to 36V, and supports dual-supply operation when the difference between the two supplies is within this range and VCC is at least 1.5V more positive than the input common-mode voltage.

Designed for efficiency, the LM2903P boasts a low supply-current drain of just 0.4mA per comparator, independent of the supply voltage. Its common-mode input voltage range includes ground, and the differential input voltage range can equal the maximum-rated supply voltage. The open-collector outputs can be connected to other open-collector outputs to achieve wired-AND logic functions, adding flexibility to your circuit designs. The output is compatible with TTL, MOS, and CMOS logic, making it a versatile choice for interfacing with various digital systems.

With a fast response time of 300ns and a low output saturation voltage, this comparator is well-suited for high-speed signal processing. The through-hole DIP package with 8 pins ensures easy integration into your PCB designs. It operates over a wide temperature range from -40°C to 125°C, ensuring reliable performance in demanding environments.
