OPA131UJ/2K5

Instrumentation, Op Amps, Buffer Amps Overview

The OPA131UJ/2K5 is a dual JFET-input operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 4 MHz and a slew rate of 10 V/µs. The device operates with supply voltages ranging from ±4.5 V to ±18 V (9 V to 36 V total). Key electrical parameters include an input bias current of 50 pA, input offset voltage of 1.5 mV, and output drive capability of 25 mA per channel. It is housed in an 8-SOIC package and supports tape-and-reel packaging.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Low-noise audio preamplifier stages
• Instrumentation amplifier front-ends

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix /2K5 corresponds to the tape-and-reel packaging format rather than tube packaging when sourcing. Confirm that the component matches the standard OPA2131 pinout if substituting into existing designs. Ensure the order quantity aligns with the manufacturer's standard reel size requirements to avoid cut-tape handling fees or availability issues.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual-channel configuration is required alongside JFET input characteristics. It serves as a direct functional replacement for single-channel variants like the OPA131UJ when two channels are needed. Consider the 8-SOIC footprint constraints during PCB layout planning. Evaluate the 25 mA output current against load requirements to ensure adequate drive capability without thermal derating.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPAy131 family of high-performance JFET operational amplifiers. The '2' in the model number indicates a dual-channel configuration, distinguishing it from the single-channel OPA131 and quad-channel OPA4131. The '/2K5' suffix specifically denotes the tape-and-reel packaging option provided by Texas Instruments for automated assembly processes.
