HLF 4558D – Low Noise Dual Operational Amplifier (DIP8) | High-Performance Audio Op-Amp | ±2V to ±22V, –40°C to +85°C | Through-Hole Package

The HLF 4558D (DIP8) is a low-noise, high-performance dual operational amplifier designed for high-fidelity audio, instrumentation, and general analog applications. It integrates two independent, internally frequency-compensated amplifiers with superior linearity and stability across a wide dual-supply range of ±2V to ±22V.

Offering low input noise, low offset voltage (<±5 mV), and low input bias current (<400 nA), the 4558D delivers clean, distortion-free signal amplification ideal for professional and consumer audio circuits. With a 3 MHz gain bandwidth and 1 V/µs slew rate, it ensures fast, accurate response. The DIP8 package is perfect for through-hole designs requiring precision and durability.
