NJM842R-TE1

Instrumentation, Op Amps, Buffer Amps Overview

The NJM842R-TE1 is a dual high-speed single-supply operational amplifier from the NJM842 series, manufactured by Nisshinbo Micro Devices. It features a maximum input offset voltage of 3.5mV and a drift of 3.5µV/°C. The device provides an 8.5V/µs slew rate and a 3.5MHz unity-gain bandwidth. Operating on a single supply ranging from 3V to 36V, it draws 4.3mA per amplifier. It includes output short-circuit protection, operates within -40°C to +125°C, and is housed in an SOP8 package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'R' corresponds to the SOP8 tape-and-reel packaging configuration before procurement. Confirm that the component meets RoHS compliance requirements for the target region. Ensure the design accommodates the specified operating temperature range of -40°C to +125°C. Validate power dissipation limits against the expected ambient thermal conditions.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual-channel amplifier requires high speed and low offset voltage under single-supply conditions. It is suitable for industrial equipment where wide voltage operation and robust protection features are necessary. Consider the 4.3mA quiescent current per channel for power budget calculations. Verify compatibility with the required PCB footprint for the SOP8 package.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the NJM842/NJM844 family of high-speed single-supply operational amplifiers. The NJM842 variant specifically offers lower quiescent current compared to the NJM844. Both share similar electrical characteristics regarding speed and offset voltage but differ in power consumption. The family is designed for general-purpose inverters and high-performance industrial applications.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The NJM844 is a related part within the same family offering identical speed and offset specifications but with higher operating current.
