Overview
The LM2901EDR2G is a single-supply quad comparator manufactured by onsemi, housed in a 14-pin SOIC package. It operates within a supply voltage range of 3.0 V to 36 V for single supply or ±1.5 V to ±18 V for split supply configurations. The device features an open-collector output capable of sinking up to 16 mA and includes input ESD protection. Electrical characteristics include a typical input bias current of 25 nA, a maximum response time of 1.3 µs, and an operating temperature range from -40°C to +105°C.
Feature Summary
- Supports both single and split power supply operations with wide voltage ranges
- Features low input bias current and low input offset voltage for precision sensing
- Includes built-in ESD clamps on inputs to enhance reliability without affecting operation
- Outputs are TTL and CMOS compatible with low saturation voltage
Applications
- Level detection circuits
- Low-level sensing applications
- Memory interface designs
Procurement Notes
Verify the specific suffix 'E' indicates extended temperature performance compared to standard variants. Confirm the 'DR2G' suffix corresponds to the SOIC-14 tape and reel packaging format. Ensure compliance with RoHS and Pb-Free requirements matches project specifications. Check for AEC-Q100 qualification if automotive grade is required, noting that NCV prefix devices hold this qualification while standard LM2901E may not.
Selection Notes
Select this component when high gain and wide bandwidth are required for level detection tasks. Consider the open-collector output structure for interfacing with various logic families. Evaluate the thermal dissipation capabilities within the SOIC-14 package for the intended ambient temperature conditions. Compare against LM339 or LM239 variants if different temperature grades or pinouts are needed.
Part Context
This part belongs to the LM2901 family of single supply quad comparators designed for consumer, automotive, and industrial electronic applications. It shares architectural similarities with the LM339 and LM239 but offers specific electrical characteristics tailored for broader supply voltage ranges and improved input bias performance.
Replacement Considerations
LM2901DR2G serves as a direct functional substitute within the same family. LM339DR2G and LM239DR2G offer similar quad comparator functionality but may differ in temperature ratings or specific electrical parameters.
