Why Choose the OPA1612?
When signal purity matters, the OPA1612 delivers. Its bipolar input topology achieves a noise density of just 1.1 nV/√Hz — among the quietest available in a DIP8 package. Combined with 0.000015% THD+N at 1 kHz, it ensures your audio path remains clean and transparent from source to output. The rail-to-rail output capability (up to 600 mV swing from the power rail at 2 kΩ loads) helps you get the absolute most from your dynamic range without clipping or compression artifacts.
Whether you are upgrading an existing audio board, experimenting with op-amp rolling, or building a precision circuit from scratch, the OPA1612 in a DIP8 footprint makes installation straightforward with any standard 8-pin IC socket.

Frequently Asked Questions
Q: What is the OPA1612 DIP8 dual op-amp IC used for?
A: The OPA1612 DIP8 is a dual operational amplifier chip used in high-fidelity audio circuits, DAC output stages, headphone amplifiers, precision instrumentation, active filters, and other applications where ultra-low noise (1.1 nV/√Hz) and ultra-low distortion (0.000015% THD+N at 1 kHz) are critical. Its DIP8 form factor makes it easy to install in standard IC sockets.
Q: Can the OPA1612 replace OPA2604 or OPA2132?
A: Yes. The OPA1612 in a DIP8 package is compatible as a drop-in replacement for OPA2604, OPA2132, and similar dual op-amps that share the standard 8-pin dual inline pinout. Always verify your circuit's supply voltage range and load requirements against the OPA1612 datasheet before substituting.
Q: What makes the OPA1612 stand out compared to other op-amps?
A: The OPA1612 combines an exceptionally low noise density of 1.1 nV/√Hz with a distortion figure of just 0.000015% at 1 kHz — both of which are among the best available in a through-hole DIP8 package. It also features rail-to-rail output with up to 600 mV swing from the supply rail at 2 kΩ loads, giving your circuit maximum dynamic headroom without signal degradation.
Q: What package type does this op-amp use?
A: This operational amplifier comes in the DIP-8 (Dual Inline Package, 8-pin) format, which fits standard 8-pin IC sockets and is commonly used in audio electronics, prototyping boards, and through-hole PCB designs.
