NJM2901CV-TE1

Comparators Overview

The NJM2901CV-TE1 is a single-supply quad voltage comparator manufactured by Nisshinbo Micro Devices. It features four independent 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). It offers an open collector output type and operates within a temperature range of -40°C to +125°C. The input common-mode voltage range includes ground during single-supply operation. Key electrical characteristics include a maximum input offset voltage of 5mV, a typical response time of 1.3μs, and a supply current of up to 2mA.

Comparators Feature Summary

• Designed specifically for single-supply operation with a wide operating voltage range.
• Features an input common-mode voltage range that includes ground potential.
• Includes internal electrostatic discharge (ESD) protection circuitry.
• Capable of direct interface 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 applications
• High voltage digital logic gates

Comparators Procurement Notes

Verify the specific package variant matches the required design constraints, as the NJM2901C series is available in both SOP14 and SSOP14 outlines. Confirm the grade requirements against datasheet specifications; the standard NJM2901C has a maximum input offset voltage of 5mV, while the A-grade variant specifies 2.5mV. Ensure thermal management aligns with the specified power dissipation ratings for the chosen mounting board configuration.

Comparators Selection Notes

Select this component when a low-power quad comparator capable of interfacing directly with standard logic families is required. The inclusion of ground-referenced input capability makes it suitable for single-supply systems where signal levels approach zero volts. Consider the A-grade version if tighter input offset voltage tolerances are necessary for precision applications. Verify that the open-collector output architecture fits the downstream load requirements.

Comparators Part Context

The NJM2901C belongs to a family of single-supply quad comparators utilizing bipolar technology. It is distinct from operational amplifiers due to its high gain and open-collector outputs optimized for switching applications rather than linear amplification. The CV suffix indicates the SSOP14 package option, providing a compact surface-mount solution compared to the standard SOP14 variant.

Comparators Replacement Considerations

The NJM2901CA serves as the higher precision alternative within the same product family, offering a reduced maximum input offset voltage of 2.5mV compared to the 5mV limit of the standard NJM2901C. Both variants share identical pinouts and electrical characteristics regarding speed and supply ranges.
