HLF LM2904 – Dual Operational Amplifier (DIP8) | Low-Power Dual Op-Amp | 3V–30V, 0°C to +70°C | Through-Hole Package

The HLF LM2904 (DIP8) is a dual low-power operational amplifier featuring two independent, high-gain, internally frequency-compensated amplifiers designed for single- or dual-supply operation. With a wide voltage range of 3V to 30V, the LM2904 provides flexibility for a variety of analog signal applications including amplification, filtering, and signal conditioning.

It offers low input offset voltage (<±7 mV), low input bias current (<250 nA), and low supply current (1 mA per amplifier), making it ideal for low-power and precision systems. The amplifier’s 1.1 MHz gain bandwidth and 0.4 V/µs slew rate ensure stable performance in general-purpose analog circuits. The DIP8 package enables easy assembly and is ideal for prototyping or industrial equipment.
