Overview
The LM2901DR is a quad differential analog comparator manufactured by Texas Instruments, housed in a 14-SOIC surface-mount package. It operates on a single or split supply voltage ranging from 2 V to 30 V. Key electrical specifications include a maximum input offset voltage of 7 mV and an input bias current of 250 nA. The device features open-collector outputs compatible with CMOS and TTL logic levels, delivering up to 6 mA per channel output current. It functions within a temperature range of -40°C to +125°C with a typical response time of 1.3 µs.
Feature Summary
- Quad differential configuration for multi-channel signal comparison
- Open-collector outputs ensuring compatibility with various logic families
- Wide single-supply operating voltage range supporting low-power applications
Applications
- Level detection circuits
- Low-level sensing systems
- Memory application interfaces
Procurement Notes
Verify the specific datasheet revision and assembly site details before integration, as manufacturing updates may occur. Confirm that the SOIC-14 footprint matches the target PCB design. Ensure compliance with RoHS3 standards if required by the end product regulations. Cross-reference the part number suffix to confirm the reel or cut tape packaging format intended for the production line.
Selection Notes
Select this component when a quad comparator with low input bias current and wide supply voltage tolerance is required. The open-collector output simplifies interfacing with different logic voltages without additional level shifting components. Consider the thermal performance of the SOIC-14 package for high-density designs. Verify that the 1.3 µs response time meets the speed requirements of the specific application signals.
Part Context
The LM2901DR belongs to the LM2901 series of analog comparators designed for general-purpose use. It shares functional similarities with other quad comparators like the LM339 but offers specific characteristics tailored for consumer, automotive, and industrial electronics. The device is part of Texas Instruments' portfolio of linear integrated circuits focused on signal conditioning and detection.
Replacement Considerations
LM2901DRE4 and LM2901DRG4 are confirmed equivalent part numbers representing the same device with different ordering suffixes.
