NJM2901N

Video Processing Overview

The NJM2901N is a single-supply quad comparator manufactured by Nisshinbo Micro Devices Inc. It features four independent channels in a 14-pin DIP package. Key electrical parameters include a maximum supply voltage of 36 V, a typical response time of 1.3 µs, and an open-collector output type. The device operates with a supply current of 1.1 mA per channel and supports an output sink current of 16 mA. Input offset voltage is typically 5 mV, with input bias current at 50 nA. Operating temperature ranges from -40°C to +85°C.

Video Processing Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout compatibility and thermal characteristics. Ensure the selected variant matches the required operating temperature range and package style for your PCB layout. Cross-reference manufacturer part numbers to avoid confusion between similar series components.

Video Processing Selection Notes

Select this component when a low-cost, general-purpose quad comparator is required for single-supply applications. Consider the open-collector output limitation if push-pull drive is necessary. Evaluate the 1.3 µs response time against signal speed requirements to ensure adequate performance for the intended application frequency.

Video Processing Part Context

This part belongs to the NJM2901 series of single-supply quad comparators. It is designed as a cost-effective solution for basic comparison tasks. The series is widely used in consumer electronics and industrial control systems where moderate speed and high input impedance are sufficient.

Video Processing Replacement Considerations

Check for direct pin-compatible alternatives such as the LM339 or LM393 series. Verify that substitute parts meet the same voltage, current, and temperature specifications before integration.
