Overview
The LM2901VDR2G 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 V to 36 V or ±1.5 V to ±18 V split supplies. Key electrical parameters include a typical input bias current of 25 nA, an input offset voltage of ±7 mV, and a response time of 1.3 µs. The device features open-collector outputs capable of sinking up to 16 mA. It supports an operating temperature range from -40 °C to +125 °C.
Feature Summary
- Supports both single and split power supply configurations for flexible system integration.
- Features low input bias current and low output saturation voltage for high sensitivity.
- Includes ESD clamps on inputs to enhance reliability without affecting operation.
- Outputs are compatible with TTL and CMOS logic families.
Applications
- Level detection circuits
- Low-level sensing applications
- Memory interface designs
Procurement Notes
Verify the specific suffix 'V' indicates the extended temperature grade (-40 °C to +125 °C) compared to standard variants. Confirm the 'DR2G' designation corresponds to the SOIC-14 tape and reel packaging format. Ensure compliance requirements such as RoHS and lead-free status match project specifications before finalizing orders.
Selection Notes
Select this component when high-speed comparison is required alongside wide common-mode input ranges extending to ground. Consider the open-collector output structure for interfacing with various logic levels. Evaluate thermal dissipation capabilities if operating near maximum ratings. Compare against NCV-prefixed automotive versions if AEC-Q100 qualification is mandatory.
Part Context
This part belongs to the LM2901 family of single-supply quad comparators, sharing architectural similarities with the LM339 and LM239 series. The 'V' suffix specifically denotes the industrial/extended temperature variant designed for harsher environments. It serves as a general-purpose analog comparator suitable for consumer, automotive, and industrial electronic applications requiring precise signal thresholding.

FAQ
What is the input common mode voltage range?
The input common mode voltage range extends from ground (0 V) to VCC minus 1.5 V.
Does the device support differential input voltages exceeding the supply voltage?
Yes, differential input voltages may be larger than the supply voltages without damaging the inputs, provided they do not go more negative than -300 mV.
