NJU7048G-TE2

Instrumentation, Op Amps, Buffer Amps Overview

The NJU7048G-TE2 is a quad-channel, high-speed CMOS operational amplifier from the NJU70 series by Nisshinbo Micro Devices. It features rail-to-rail input and output capabilities with a typical slew rate of 9 V/µs and a gain-bandwidth product of 5 MHz. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V, drawing a maximum supply current of 8.4 mA across all channels. Key electrical characteristics include a maximum input offset voltage of 5 mV, an input bias current of 1 pA, and an open-loop voltage gain of 110 dB. It supports an operating temperature range from -40°C to +125°C and provides 110 mA short-circuit output current.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package type SSOP14 matches the design requirements. Confirm that the supply voltage and load conditions align with the specified electrical characteristics. Ensure thermal management considerations are addressed for the SSOP14 package within the operating temperature range. Check for any specific handling precautions related to ESD protection during assembly.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a quad-channel configuration is required alongside high-speed performance and rail-to-rail I/O. It is suitable for designs needing low input bias current and wide common-mode input range. Consider the SSOP14 package constraints regarding board space and thermal dissipation compared to other available packages in the NJU70 series.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the NJU70 series of high-speed CMOS operational amplifiers. The series includes single (NJU7046), dual (NJU7047), and quad (NJU7048) channel variants. All share similar electrical specifications but differ in channel count and package options. The NJU7048 specifically offers four independent amplifiers in a 14-pin format.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes within the same family include NJU7047 variants for dual-channel needs or NJU7046 for single-channel. Verify pin compatibility and package dimensions before substitution. Other high-speed op-amps may require circuit redesign due to differences in slew rate, bandwidth, or input bias current specifications.
