NJU7043RB1-TE1

Overview

The NJU7043RB1-TE1 is a dual high-current operational amplifier manufactured by Nisshinbo Micro Devices using CMOS technology. It features an 800 kHz gain-bandwidth product and a 700 mV/us slew rate. The device operates on a single supply voltage ranging from 1.8 V to 5.5 V with a typical operating current of 1 mA per channel. Key electrical specifications include a maximum input offset voltage of 10 mV, an input bias current of 1 pA, and a common-mode rejection ratio of 42 dB. The input voltage noise density is 40 nV/√Hz. It is housed in a TVSP-8 surface-mount package and supports an industrial temperature range from -40°C to +85°C.

Feature Summary

• High output current capability for driving low impedance loads
• Ultra-low input bias current suitable for high-impedance sensor interfaces
• Rail-to-rail input and output operation maximizing dynamic range
• CMOS construction ensuring low power consumption

Applications

• Current sensing circuits
• Sensor signal amplification
• Photodiode pre-amplifiers
• Buffer stages for ADC/DAC interfaces

Procurement Notes

Verify the specific suffix TE1 against the required reel quantity and tape specifications during procurement. Confirm that the TVSP-8 package variant matches the PCB footprint design. Ensure the component meets RoHS compliance requirements for the target assembly process. Cross-reference the manufacturer part number with official datasheets to confirm pinout compatibility before finalizing orders.

Selection Notes

Select this component when high drive current is required alongside low input bias characteristics. The rail-to-rail I/O makes it suitable for single-supply applications near ground or rail potentials. Consider the 800 kHz bandwidth for moderate-speed signal processing tasks. Evaluate the TVSP-8 package constraints against available board space and thermal management requirements.

Part Context

This device belongs to the NJU7043 series of dual operational amplifiers designed for general-purpose analog signal processing. The series emphasizes high current drive capabilities combined with low power consumption typical of CMOS technology. It serves as a versatile solution for battery-powered devices requiring efficient signal conditioning without significant voltage headroom loss.

Replacement Considerations

Check for NJU7043M-TE1 (DMP-8 package) or NJU7043V-TE1 (SSOP-8 package) if package form factor changes are acceptable. Verify electrical parameter equivalence for direct substitution.
