Overview
The LM2901M/ELLD606 is a quad differential analog comparator manufactured by Texas Instruments, housed in a 14-SOIC package. It features four independent open-collector output stages designed for low-power applications with a maximum input offset voltage of 7mV at 5V and an input bias current of 0.25µA. The device operates within a temperature range of -40°C to 85°C and supports a quiescent current of up to 2.5mA.
Feature Summary
- Quad differential configuration with four independent comparators
- Low offset voltage specification for precision sensing
- Open-collector output stages for flexible interfacing
Applications
- General-purpose signal comparison circuits
- Threshold detection systems
- Voltage monitoring applications
Procurement Notes
Verify the specific suffix ELLD606 against official Texas Instruments documentation to confirm pinout and electrical characteristics match your design requirements. Ensure the 14-SOIC package dimensions are compatible with your PCB footprint. Cross-reference the operating temperature range and output drive capabilities with system specifications before finalizing procurement.
Selection Notes
Select this component when a quad comparator solution is required with low offset voltage characteristics. The open-collector outputs allow for wired-AND configurations or level shifting. Consider the 2.5mA quiescent current limit and the -40°C to 85°C operating range to ensure compatibility with environmental conditions.
Part Context
This part belongs to the LM2901 family of low-power, low-offset voltage quad comparators from Texas Instruments. It shares functional similarities with other variants like the LM2901BWRTERQ1 but differs in packaging and specific electrical tolerances. The ELLD606 suffix indicates a specific tape-and-reel or bulk packaging variant within the standard SOIC form factor.
Replacement Considerations
The LM2901M/NOPB is a documented equivalent offering similar quad comparator functionality in a comparable package. Verify that the input offset voltage and bias current specifications of the substitute meet the original design constraints.
