Key Features
- Dual FET-input op-amp with 20 MHz gain-bandwidth product for high-fidelity audio amplification
- Ultra-low THD+N (0.0003% at 1 kHz) suitable for audiophile preamplifiers and studio equipment
- Wide supply voltage range of ±4.5 V to ±24 V supports both portable and rack-mount audio designs
Applications
The OPA2604AP is a premier choice for high-end audio preamplifiers, active crossovers, and analog mixing consoles where ultra-low total harmonic distortion below 0.0003% at 1 kHz is required. Its wide ±24 V supply range and 20 MHz bandwidth enable use in professional studio equipment, DAC output stages, and phono pre-amplifiers. The through-hole 8-pin PDIP package simplifies prototyping and service-friendly designs in audiophile and musical instrument applications.

Frequently Asked Questions
What gain-bandwidth product and distortion specification does the OPA2604AP offer for audio circuits?
The OPA2604AP provides a 20 MHz gain-bandwidth product and typical total harmonic distortion plus noise (THD+N) of just 0.0003% at 1 kHz into a 600-ohm load. These figures make it one of the lowest-distortion dual op-amps available in an 8-pin PDIP, ideal for audiophile preamplifiers and precision active filters.
What supply voltage range does the OPA2604AP support, and does this affect headroom in professional audio gear?
The OPA2604AP operates from ±4.5 V to ±24 V split supplies, giving up to 48 V total supply headroom. At ±18 V, the output swing approaches ±16 V, delivering over 30 dBu of headroom — well above the +24 dBu professional line level — without clipping in mixing consoles or mastering equipment.
When should an engineer choose the OPA2604AP over a standard JFET op-amp like the TL072 for an active filter?
Engineers should choose the OPA2604AP over the TL072 when THD below 0.001% and bandwidth above 4 MHz at unity gain are required. At a gain of 10 and 20 kHz, the OPA2604AP maintains distortion below 0.001% while the TL072 degrades to roughly 0.01%, a 10x difference that is audible in precision active crossover networks and equalizer designs.
What package does the OPA2604AP use and how does it simplify prototyping?
The OPA2604AP uses an 8-pin PDIP (plastic dual in-line package) with 2.54 mm (100-mil) pin pitch, compatible with standard breadboards, perfboards, and DIP sockets. The through-hole format allows quick substitution during prototyping without soldering, and the 8-pin pinout is interchangeable with other dual op-amp DIP packages, reducing redesign effort.
