NJU7043D

Instrumentation, Op Amps, Buffer Amps Overview

The NJU7043D is a dual CMOS operational amplifier featuring rail-to-rail input and output capabilities. It operates within a supply voltage range of 1.8V to 5.5V, providing a typical high output current of 40mA at Vo=0V. The device exhibits a unity gain bandwidth of 0.8MHz and a slew rate of 0.7V/µs. Key electrical characteristics include a maximum input offset voltage of 10mV, a typical operating current of 600µA for both amplifiers, and an input bias current of 1pA. It supports ground sensing and functions across a temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the Not Recommended for New Design (NRND) status before initiating any new procurement or design-in processes. Confirm that existing inventory levels meet long-term requirements as future production may be discontinued. Ensure compatibility with DIP-8 through-hole mounting specifications during final assembly validation.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when single-supply operation between 1.8V and 5.5V is required alongside rail-to-rail performance. Consider the 40mA output drive capability for driving low-impedance loads directly. Evaluate the 1pA input bias current suitability for high-impedance sensor interfaces. Verify package availability against board space constraints for the DIP-8 form factor.

Instrumentation, Op Amps, Buffer Amps Part Context

The NJU7043D belongs to the NJU7043 series of dual CMOS operational amplifiers manufactured by Nisshinbo Micro Devices. This series includes variants in different packages such as SSOP8 and MSOP8. The D suffix specifically denotes the DIP-8 package configuration. The product line emphasizes low power consumption combined with high output drive strength for general-purpose analog applications.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for direct pin-compatible alternatives from the same manufacturer family if DIP-8 packaging is mandatory. Review datasheets for other dual op-amps offering similar 40mA output current and rail-to-rail I/O specifications. Ensure replacement parts maintain the 1.8V minimum supply voltage requirement.
