OPA2134UA/2K5 is a Texas Instruments (Burr-Brown) OPA2134 SoundPlus dual audio operational amplifier in SOIC-8, 2500-piece tape and reel — true FET input (5 pA bias current), 0.00008% THD+N at 1 kHz, 8 nV/√Hz noise, 20 V/µs slew rate, 8 MHz gain-bandwidth, ±2.5 V to ±18 V supplies, unity-gain stable with no phase inversion. The /2K5 code is the selection point: the same OPA2134UA die on 2500-piece reel for production — prototypes and small runs use the tube OPA2134UA, and the PDIP OPA2134PA for through-hole builds. Selection advice: the FET input plus 0.00008% distortion is why this part owns the audio preamp, active-filter and line-driver sockets — high source impedances see essentially no bias-current error, and the distortion floor stays below what the rest of the signal chain can resolve. It is not rail-to-rail (swings to within ~1 V of rails), so for single 5 V rail-to-rail work choose a different family. Evidence: TI OPA2134 datasheet package addendum confirms UA = SOIC-8, 2500-piece reel, and the audio performance specs. Match the full OPA2134UA/2K5 code.
Ordering-code highlights reviewed against official manufacturer documentation.
OPA2134 is available in the following manufacturer order codes. They share the same OPA2134 design; the table highlights package, packing and ordering differences. Quote the exact code your BOM needs.
| Order code | Package | Packing | Key difference |
|---|---|---|---|
| OPA2134UA | SOIC-8 | — | — |
| OPA2134UA/2K5 | SOIC-8 | LARGE T&R | Same SOIC-8 package as OPA2134UA; this difference alone does not require PCB pad changes; factory packing is LARGE T&R, 2,500 per pack; OPA2134UA is TUBE, 75 per pack. |

Browse existing catalog records — same series first, then the same category and manufacturer. These are not confirmed replacements; compatibility requires engineering review.
These are order-code variants of the same Texas Instruments series. They share the core design; the ordering code selects the exact configuration — OPA2134UA (SOIC-8). OPA2134UA/2K5 itself is the SOIC-8 configuration. A code that differs by even one character may be a different device, so always quote the complete code exactly as it appears on your BOM.
From the verified technical profile: Package code: SOIC (D); Pin count: 8; Operating temperature: -40 to 85 °C. These are the catalog-recorded values for OPA2134UA/2K5 — always re-check them against the manufacturer datasheet revision quoted on your BOM before finalizing the design.
