Overview
The LM2901MX/NOPB is a low-power, low-offset voltage quad comparator manufactured by Texas Instruments. It features four independent differential comparators in a single package. The device operates with a supply voltage range of 2 V to 36 V and draws a typical operating current of 800 µA per channel. It offers an input offset voltage of 3.5 mV and an input bias current of 25 nA. The output type is open collector, capable of sinking up to 20 mA. It supports propagation delays of 300 ns and 1000 ns depending on conditions. The component functions within a temperature range of -40°C to +125°C and is housed in a 14-SOIC package.
Feature Summary
- Integrates four independent differential comparators for multi-channel signal processing
- Provides low power consumption suitable for battery-operated applications
- Features low input offset voltage for high-precision threshold detection
- Supports wide single-supply voltage operation for flexible system integration
Applications
- Battery-powered monitoring systems
- Threshold detection circuits
- Voltage level sensing
- Over-voltage protection circuits
Procurement Notes
Verify the exact part number against the manufacturer's datasheet to ensure compatibility with specific design requirements. Confirm that the SOIC-14 package dimensions match the PCB footprint. Check for RoHS compliance status if environmental regulations apply to the final product. Ensure the supply voltage range aligns with the system's power rails. Validate the operating temperature range against the intended application environment.
Selection Notes
Select this component when multiple independent comparison channels are required in a compact form factor. Consider the low offset voltage specification for applications requiring precise voltage thresholds. Evaluate the open-collector output capability for interfacing with different logic families. Assess the power consumption benefits for energy-sensitive designs compared to standard comparators.
Part Context
The LM2901 series belongs to Texas Instruments' family of low-power analog comparators. This specific variant includes the NOPB suffix indicating lead-free and RoHS-compliant manufacturing. It serves as a modern replacement for older legacy comparator parts while maintaining pin compatibility and functional equivalence. The MX suffix denotes the SOIC surface-mount package option.
