NJM2747V-TE2

Overview

The NJM2747V-TE2 is a quad operational amplifier manufactured by Nisshinbo Micro Devices. It features a gain-bandwidth product of 10 MHz and a slew rate of 3.5 V/µs. The device operates on a single supply voltage ranging from 2.5 V to 14 V with a typical operating current of 4 mA per channel. Key electrical specifications include an input offset voltage of 1 mV, input bias current of 350 nA, and input voltage noise density of 10 nV/√Hz. It offers rail-to-rail output capability, a common-mode rejection ratio of 60 dB, and a power supply rejection ratio of 80 dB. Total harmonic distortion plus noise is specified at 0.001%. The component is housed in an SSOP-14 package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Quad configuration providing four independent high-speed operational amplifiers within a single integrated circuit.
• Rail-to-rail output stage design enabling maximum dynamic signal swing across the full supply voltage range.
• Low power consumption characteristics suitable for battery-operated and portable electronic applications.

Applications

• Portable instrumentation requiring low power and high accuracy
• Battery-powered sensor signal conditioning circuits
• Audio pre-amplification stages

Procurement Notes

Verify the specific suffix TE2 indicates the reel packaging format when sourcing components. Confirm that the SSOP-14 pinout matches the target PCB footprint layout. Ensure the operating environment remains within the specified -40°C to +85°C temperature limits to maintain guaranteed electrical performance parameters.

Selection Notes

Select this component when a quad amplifier topology is required alongside rail-to-rail output capabilities. The 10 MHz bandwidth and 3.5 V/µs slew rate support moderate-speed signal processing tasks. Consider the 1 mV input offset voltage specification for precision requirements where external trimming is not feasible.

Part Context

This part belongs to the NJM274x series of single-supply operational amplifiers from Nisshinbo Micro Devices. The series includes dual-channel variants such as the NJM2746V and quad-channel variants like the NJM2745V. The NJM2747V-TE2 specifically provides four channels in an SSOP-14 package, distinguishing it from the dual-channel NJM2746V which uses an SSOP-8 package.

Replacement Considerations

The NJM2746V-TE2 serves as a functional substitute if only two channels are required, offering identical electrical specifications but in an SSOP-8 package. Designers must account for the difference in pin count and physical footprint when transitioning between these variants.
