NCS325SN2T1G

Instrumentation, Op Amps, Buffer Amps Overview

The NCS325SN2T1G is a single-channel precision zero-drift operational amplifier from onsemi, housed in an SOT-23-5 package. It features a supply voltage range of 1.8 V to 5.5 V and operates within a temperature range of -40°C to +125°C. Key electrical parameters include a maximum offset voltage of 50 µV at 25°C, a drift of 0.25 µV/°C, and a typical quiescent current of 21 µA. The device offers rail-to-rail input and output capabilities with a gain-bandwidth product of 350 kHz.

• Temperature measurements
• Transducer applications
• Electronic scales
• Medical instrumentation
• Current sensing

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix SN2T1G corresponds to the SOT-23-5 package and tape & reel shipping configuration. Confirm RoHS compliance and Pb-free status as indicated by the G or microdot marking. Ensure the application environment stays within the specified operating temperature and supply voltage limits to maintain guaranteed performance.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for precision DC applications requiring minimal offset voltage and drift without external trimming. The low quiescent current makes it suitable for battery-powered designs. Verify that the required bandwidth and slew rate meet system specifications, as the device is optimized for precision rather than high-speed transient response.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the NCS325 family of CMOS operational amplifiers, which also includes dual-channel (NCS2325) and quad-channel (NCS4325) variants. All members share the same zero-drift architecture and electrical characteristics but differ in channel count and available packages such as Micro8, SOIC-8, and SOIC-14.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional substitutes within the same family include NCS2325DR2G and NCS4325DR2G, though these offer multiple channels and different pinouts. No other single-channel equivalents are explicitly confirmed in the provided documentation.
