NJM2901CAV-TE1

Comparators Overview

The NJM2901CAV-TE1 is a single-supply quad comparator manufactured by Nisshinbo Micro Devices. It features four independent voltage comparators designed for operation from a single power supply over a wide voltage range of +2V to +36V, with split supply operation also supported. The device utilizes bipolar technology and includes internal ESD protection rated at ±2000V (HBM). Key electrical specifications include an input offset voltage of 2.5mV maximum, an open-loop voltage gain of 106dB typical, and a response time of 1.3μs. It operates within a temperature range of -40°C to +125°C and is housed in an SSOP-14 package.

Comparators Feature Summary

• Features four independent voltage comparators optimized for single-supply operation across a wide voltage range.
• Includes internal electrostatic discharge protection rated at ±2000V under the human body model.
• Provides open collector outputs that allow direct interfacing with TTL and MOS logic families.

Comparators Applications

• Limit comparators
• Simple analog-to-digital converters
• Pulse, square-wave, and time delay generators
• Wide range VCO circuits
• High voltage digital logic gates

Comparators Procurement Notes

Verify the specific ordering suffix 'A' corresponds to the A-grade input offset voltage specification of 2.5mV maximum, distinct from the standard C-grade. Confirm the 'V' suffix indicates the SSOP-14 package variant rather than the SOP-14 option. Ensure the TE1 designation matches the required reel packaging format for automated assembly processes.

Comparators Selection Notes

Select this component when high precision is required due to its low 2.5mV maximum input offset voltage grade. Choose it for applications requiring direct interface with standard logic families without additional buffering. Consider the wide common-mode input voltage range including ground as a key selection factor for single-supply designs.

Comparators Part Context

This part belongs to the NJM2901C/NJM2901CA series of single-supply quad comparators. The series is characterized by low power supply current drain that remains independent of the supply voltage magnitude. It is designed to operate effectively from both plus and minus power supplies, offering advantages over standard comparators in terms of power efficiency.

Comparators Replacement Considerations

The NJM2901CG-TE2 serves as a comparable alternative within the same family, offering similar quad comparator functionality but packaged in SOP-14 instead of SSOP-14. Both parts share the same core electrical characteristics and pinout configuration.

Comparators FAQ

What is the difference between the NJM2901C and NJM2901CA grades?

The NJM2901CA is the A-grade version with a maximum input offset voltage of 2.5mV, whereas the standard NJM2901C is the normal-grade version with a maximum input offset voltage of 5mV.

Can the NJM2901CAV-TE1 operate with split power supplies?

Yes, while designed specifically for single power supply operation, the device supports operation from split power supplies as well.
