OPA2197IDR

Instrumentation, Op Amps, Buffer Amps Overview

The OPA2197IDR is a dual precision operational amplifier manufactured by Texas Instruments, housed in an SOIC-8 surface-mount package. It features rail-to-rail input and output capabilities with a gain-bandwidth product of 10 MHz and a slew rate of 20 V/µs. The device operates on supply voltages ranging from 4.5 V to 36 V (single) or ±2.25 V to ±18 V (dual). Key electrical specifications include a maximum input offset voltage of 25 µV, input bias current of 5 pA, and input noise current density of 1.5 fA/√Hz. It delivers 65 mA per channel output current with a typical operating supply current of 1 mA.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'IDR' corresponds to the SOIC-8 tape-and-reel packaging configuration. Confirm that the component meets RoHS compliance requirements as indicated in manufacturer documentation. Ensure compatibility with standard surface-mount assembly processes and check moisture sensitivity levels prior to soldering.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when dual-channel precision amplification with rail-to-rail swing is required. It serves as a higher-performance alternative to the OPA2196 series due to its lower offset voltage and higher bandwidth. Consider the SOIC-8 package constraints and thermal characteristics for PCB layout planning.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPA2197 family of precision operational amplifiers. It shares functional similarities with the single-channel OPA197 and automotive-grade OPA2197-Q1 variants. The 'IDR' designation specifically identifies the industrial temperature range version packaged in an SOIC-8 reel format.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible alternatives within the same family include OPA2197ID (SOIC-8 tube) and OPA2197IDGKR (VSSOP-8). For automotive applications, verify if OPA2197QDGKRQ1 meets the specific reliability standards required.
