HLF 4558 – Dual Operational Amplifier (DIP8) | High-Performance Dual Op-Amp | ±2V to ±22V, 0°C to +70°C | Through-Hole Package

The HLF 4558 (DIP8) is a dual high-performance operational amplifier featuring low noise, low offset voltage, and wide bandwidth, making it ideal for precision audio, signal processing, and general-purpose analog circuits. It combines two internally frequency-compensated op-amps with superior linearity and stability across a wide dual-supply range (±2V to ±22V).

Offering a gain bandwidth product of 3 MHz and a slew rate of 1.7 V/µs, the 4558 provides fast response and accurate amplification. Its low input offset voltage (<±5 mV) and low input bias current (<250 nA) make it suitable for high-fidelity and instrumentation-grade applications. The robust DIP8 package ensures easy integration into standard through-hole designs.
