NJU7051D#

Instrumentation, Op Amps, Buffer Amps Overview

The NJU7051D is a single-channel C-MOS operational amplifier designed for low-voltage, single-supply applications. It features a maximum input offset voltage of 2 mV and an extremely low input bias current of 1 pA typ., enabling precise amplification of small signals near ground level. The device operates on supply voltages ranging from 1 V to 16 V with a typical operating current of 15 μA per circuit. It supports rail-to-rail output swing and includes internal compensation. A unique feature of the NJU7051 variant is the provision for external offset null adjustment.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the specific part number NJU7051D corresponds to the DMP8 package as documented in the official datasheet. Confirm that the ordering suffix matches the manufacturer's standard nomenclature for this component series. Ensure compatibility with single-supply requirements and check for any specific handling instructions related to CMOS technology inputs.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing circuits that require minimal quiescent current and high precision at low supply voltages. The availability of external offset null adjustment makes it suitable for applications demanding strict DC accuracy without relying solely on internal trimming. Consider the DMP8 package constraints for PCB layout and thermal management in compact designs.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the NJU7051/52 series of low input offset voltage C-MOS operational amplifiers manufactured by Nisshinbo Micro Devices. The series includes both single (NJU7051) and dual (NJU7052) channel variants. The NJU7051 is distinguished by its ability to perform external offset null adjustments, offering greater flexibility for precision applications compared to standard fixed-offset amplifiers.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the same series. Verify that any substitute maintains the 1 pA input bias current and 2 mV max offset voltage specifications to ensure equivalent performance in low-signal applications.
