Overview
The LP2901N is a quad, low-power, general-purpose differential comparator manufactured by Texas Instruments. It features four independent channels within a single 14-pin PDIP package. The device operates on a single power supply ranging from 5 V to 28 V. It exhibits an open-collector output type and has a typical response time of 8 µs. The operating temperature range spans from -40 °C to +85 °C.
Feature Summary
- Integrates four independent general-purpose differential comparators in a single package
- Designed for low-power operation with minimal supply current consumption
- Features open-collector outputs compatible with various logic families
Applications
- General-purpose voltage monitoring circuits
- Threshold detection systems
- Simple analog-to-digital conversion interfaces
Procurement Notes
Verify the specific manufacturer source, as the LP2901N designation may appear under different brand names such as National Semiconductor or STMicroelectronics due to historical industry acquisitions. Confirm that the component matches the 14-pin PDIP through-hole package specification. Ensure the datasheet aligns with the required 5 V to 28 V single-supply operation and 8 µs response time characteristics before integration into designs.
Selection Notes
Select this component when a cost-effective solution for multiple comparison tasks is required without the need for high-speed performance. It is suitable for applications where the 8 µs response time is sufficient and low quiescent current is a priority. Consider alternative packages like SOIC if surface-mount technology is preferred over through-hole mounting.
Part Context
This part belongs to the broader family of low-power quad comparators produced by Texas Instruments and its predecessor entities. It serves as a standard discrete solution for basic signal conditioning and threshold sensing tasks in consumer and industrial electronics. The device is often used in conjunction with resistive dividers to monitor battery levels or system voltages.
Replacement Considerations
The LM2901N is a functionally equivalent part number within the same product family. Other variants include the LP2901IDRQ1 for automotive applications in SOIC packaging.
