OPA4227UA

Instrumentation, Op Amps, Buffer Amps Overview

The OPA4227UA is a quad high-precision, low-noise operational amplifier manufactured by Texas Instruments. It features an 8 MHz gain-bandwidth product and a 2.3 V/us slew rate. The device operates within a supply voltage range of 5 V to 36 V (±2.5 V to ±18 V). Key electrical specifications include a maximum input offset voltage of 200 uV, input bias current of 10 nA, and input voltage noise density of 3 nV/sqrt Hz. It provides a common-mode rejection ratio of 138 dB and delivers 45 mA output current per channel. The component is housed in a 14-SOIC package and supports operation from -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix against official documentation, as variants like /2K5 indicate different packaging formats such as tape and reel rather than tube. Confirm RoHS compliance status and moisture sensitivity level requirements prior to ordering. Ensure the selected package matches the intended surface mount assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing circuits requiring multiple channels with rail-to-rail I/O and low noise specifications. The 14-SOIC package suits applications needing four independent amplifiers in a compact footprint. Consider the 200 uV maximum offset voltage for precision DC applications. Verify that the 8 MHz bandwidth meets the system's frequency response requirements without introducing phase distortion.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the OPAx227 series of high-precision operational amplifiers. It shares core architectural similarities with the dual-channel OPA2227UA but integrates four independent amplifier circuits. The series is characterized by low noise and high common-mode rejection ratios suitable for demanding analog signal processing tasks.
