LM2901DR FAQs

1.Q: How does the LM2901DR compare to similar parts like the LM339?

A: The LM2901DR is functionally equivalent to the LM339 but offers tighter specifications (e.g., lower bias current) and automotive-grade reliability. Both are pin-compatible.

2.Q: What are the recommended operating conditions for the LM2901DR?

A: Supply voltage: 2V to 36V, operating temperature: -40°C to +125°C, and input voltage range: 0V to (VCC -1.5V). Ensure output pull-up resistors are used.

3.Q: What package does the LM2901DR use, and is it RoHS compliant?

A: It comes in a 14-pin SOP (Small Outline Package) with dimensions 8.65mm x 3.9mm. It is RoHS and REACH compliant (terminal finish: Ni/Pd/Au).

4.Q: What is the response time of the LM2901DR?

A: The typical response time is 1300ns (1.3µs) under a 5V supply with a 5mV overdrive.

5.Q: What are the absolute maximum ratings for the LM2901DR?

A: Supply voltage: 36V max, input voltage: -0.3V to +36V, output sink current: 16mA per channel, and operating temperature: -40°C to +125°C. Exceeding these may damage the device.

6.Q: What are typical applications for the LM2901DR?

A: It’s used in voltage monitoring, window comparators, motor control, battery-powered systems, and industrial/automotive circuits requiring multi-channel signal comparison.

7.Q: What are the key features of the LM2901DR?

A: Key features include: 4 independent comparators, open-collector outputs, wide supply range (up to 36V), low input bias current (0.25µA max), and automotive-grade temperature range (-40°C to +125°C).

8.Q: What is the pinout configuration of the LM2901DR quad comparator?

A: The LM2901DR has 14 pins in a SOP-14 package: Pins 1–4 and 5–8 are inputs/outputs for the four comparators, Pin 14 is VCC (+5V typical), and Pin 7 is GND. Refer to the datasheet for the full pinout diagram.
