NJU7027RB1-TE2

Instrumentation, Op Amps, Buffer Amps Overview

The NJU7027RB1-TE2 is a dual-channel, rail-to-rail output CMOS operational amplifier from the NJU70 series. It operates on a single supply of 1.8V to 5.5V or dual supplies of ±0.9V to ±2.75V. Key electrical parameters include a gain-bandwidth product of 160kHz, a typical supply current of 26µA per channel, and an input offset voltage of 4mV maximum. The device features ground sensing capability with a common-mode input voltage range extending to the negative rail.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail output capability allows signal swing within 50mV of the supply rails under standard loading conditions.
• Ground sense functionality enables accurate signal processing when the common-mode input voltage includes the negative supply rail.
• High RF noise immunity reduces susceptibility to malfunctions caused by external radio frequency interference.

Instrumentation, Op Amps, Buffer Amps Applications

• Battery-powered instruments
• Current sensor amplifiers
• Voltage and current monitoring circuits
• Photodiode amplifiers

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package variant (MSOP8 or DFN8-U1) required for the design, as the base part number covers multiple physical packages. Confirm that the ordering suffix matches the intended mechanical footprint and thermal pad configuration. Ensure the selected component meets the environmental operating temperature range specified in the datasheet for the target application environment.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring low power consumption alongside rail-to-rail performance. The dual-channel configuration is suitable for space-constrained designs needing two independent amplification paths. Consider the 160kHz bandwidth limit when designing for higher frequency signals. The low bias current makes it appropriate for high-impedance source applications such as charge amplifiers.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the NJU70 series of low-power CMOS operational amplifiers manufactured by Nisshinbo Micro Devices. The series includes single (NJU7026), dual (NJU7027), and quad (NJU7028) variants sharing identical electrical characteristics but differing in channel count and package options. The NJU7027 specifically provides a dual-channel solution optimized for portable electronics.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Compatible substitutes within the same family include NJU7026 (single channel) and NJU7028 (quad channel). Verify pin compatibility if replacing with other NJU70 series devices, noting that package dimensions vary between SOT-23, MSOP, and DFN formats.
