| FFF Compatibility | The pinout (Pins 1-8 assignments) and physical footprint are identical to the OPA2604AU in the 8-SOIC package.Shares the exact standard 8-SOIC package dimensions (3.90 mm body width).Maximum supply voltage is limited to 36 V (±18 V) compared to the OPA2604's 48 V (±24 V). Functionally superior if operated within the ±18 V rail limit. | The pinout and footprint are identical to the OPA2604AU in the 8-SOIC package.Shares the exact standard 8-SOIC package dimensions (3.90 mm body width).Maximum supply voltage is limited to 36 V (±18 V) compared to the OPA2604's 48 V (±24 V), and Gain Bandwidth Product is lower (11 MHz vs 20 MHz). | ||
 AI Summary | OPA2604AU by Texas Instruments: Standard (General Purpose) Amplifier 2 Circuit Differential 8-SOIC. | The OPA1656 is a modern, high-performance CMOS audio operational amplifier designed by TI to succeed legacy audio op-amps. It offers significantly lower distortion, lower noise, and much higher bandwidth, but its maximum supply voltage is limited to ±18 V. It is an active and highly recommended replacement for designs operating within this voltage limit.
| The OPA1642 is a modern JFET-input SoundPlus operational amplifier that offers an excellent combination of low noise, low distortion, and very low input bias current. It is an ideal active alternative for high-impedance audio applications that do not exceed the ±18 V supply voltage rails.

You searched one part. Parter watches your whole BOM.
All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
Frequently asked questions
Yes. The Texas Instruments OPA2604AU is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
The closest qualified second sources for the Texas Instruments OPA2604AU are the OPA1656IDR (Texas Instruments) and the OPA1642AIDR (Texas Instruments), out of 5 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the OPA2604AU are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The OPA2604AU (Texas Instruments) is a part in the Linear category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
