OPA197IDR

Instrumentation, Op Amps, Buffer Amps Overview

The OPA197IDR is a quad precision operational amplifier manufactured by Texas Instruments, housed in a 14-pin SOIC package. It features a gain-bandwidth product of 10 MHz and a slew rate of 20 V/us. The device operates on supply voltages ranging from 4.5 V to 36 V with a quiescent current of 1 mA per channel. Key electrical specifications include an input offset voltage of 25 uV, input bias current of 5 pA, and input noise current density of 1.5 fA. It provides rail-to-rail input and output capabilities, a common-mode rejection ratio of 140 dB, and an input voltage noise density of 5.5 nV/sqrt Hz.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Quad configuration providing four independent precision amplifiers within a single integrated circuit.
• Rail-to-rail input and output stages enabling full signal swing across the entire supply voltage range.
• Ultra-low input bias current specification suitable for high-impedance sensor interfacing applications.

Instrumentation, Op Amps, Buffer Amps Applications

• Precision data acquisition systems requiring multi-channel signal conditioning

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'IDR' corresponds to the SOIC-14 surface-mount package variant. Confirm that the component meets RoHS compliance requirements for your target market. Ensure moisture sensitivity level handling procedures are followed during assembly to prevent package damage.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when multiple precision channels are required in a compact footprint. Compare against single or dual variants like OPA197ID or OPA2197IDR if fewer channels suffice. Evaluate thermal dissipation requirements for the SOIC-14 package under maximum load conditions.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPAx197 family of 36-V precision operational amplifiers. The family includes single (OPA197), dual (OPA2197), and quad (OPA4197) configurations sharing identical core electrical characteristics. The ID suffix denotes the industrial temperature range and SOIC package style.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional substitutes within the same family include OPA197ID for single-channel needs and OPA2197IDR for dual-channel applications. Verify pin compatibility and package dimensions before substituting with other manufacturer precision amplifiers.
