OPA227U/2K5G4

Instrumentation, Op Amps, Buffer Amps Overview

The OPA227U/2K5G4 is a single-channel precision operational amplifier manufactured by Texas Instruments. It features an 8 MHz gain-bandwidth product and a 2.3 V/us slew rate. Key electrical parameters include a maximum input offset voltage of 5 uV, an input bias current of 2.5 nA, and an input voltage noise density of 3 nV/sqrt Hz. The device operates within a supply voltage range of 5 V to 36 V with a typical operating current of 3.7 mA. It provides a common-mode rejection ratio of 138 dB and supports rail-to-rail input and output capabilities. The component is housed in an SOIC-8 surface-mount package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's official documentation to confirm RoHS compliance status and lead times. Ensure the SOIC-8 package dimensions match the target PCB footprint. Confirm moisture sensitivity level requirements for the assembly process. Cross-reference the datasheet revision date to ensure parameter accuracy.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high precision and low noise are required in a single-channel configuration. The rail-to-rail I/O feature makes it suitable for low-voltage applications where maximizing signal swing is critical. Compare the 5 uV offset voltage against system error budgets. Consider the 3.7 mA supply current for power-constrained designs.
