NCS2325DR2G

Instrumentation, Op Amps, Buffer Amps Overview

The NCS2325DR2G is a dual-channel precision zero-drift operational amplifier from onsemi, housed in an SOIC-8 package. It features a Zero-Drift architecture for continuous auto-calibration, ensuring very low offset voltage (14 µV typ) and near-zero drift over time and temperature (0.25 µV/°C max). The device operates on a supply voltage range of 1.8 V to 5.5 V with a typical quiescent current of 21 µA. Key electrical parameters include a gain-bandwidth product of 270 kHz, a slew rate of 160 mV/µs at 5.5 V, and rail-to-rail input and output capabilities.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the ordering suffix 'D' corresponds to the SOIC-8 package and 'R2G' indicates tape and reel packaging with lead-free compliance. Confirm the manufacturer part number matches the specific datasheet revision required for your design. Ensure the component meets RoHS and REACH standards as specified in the official documentation before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for precision DC applications requiring low offset and low power consumption. The dual-channel configuration in an SOIC-8 package offers a balance of performance and space efficiency compared to single-channel or quad-channel variants. Consider the 270 kHz bandwidth and 160 mV/µs slew rate for signal conditioning tasks within these dynamic limits.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the NCS2325 series of CMOS operational amplifiers, which also includes single-channel (NCS325) and quad-channel (NCS4325) versions. All variants share the same core Zero-Drift technology and electrical characteristics, differing primarily in channel count and available package options such as SOT23-5, Micro8, and SOIC-14.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional substitutes within the same family include the NCS2325DMR2G, which shares identical electrical specifications but utilizes a Micro8/MSOP-8 package instead of SOIC-8. Designers must verify pinout compatibility and thermal dissipation requirements when considering package changes.
