This mono Class AB audio amplifier provides 250mW of output power into a 32Ω load, operating from a supply voltage as low as 2V up to 6V. Its standby feature minimizes power draw when idle, making it ideal for battery-operated devices. Housed in a through-hole 8-DIP package, it is easy to integrate into prototypes and low-volume products. Typical applications include portable radios, headphone amplifiers, and intercoms where low power and simplicity are key.
- Low Voltage Operation: Works from 2V to 6V, compatible with 2-cell alkaline or single Li-ion batteries.
- Standby Mode: Reduces power consumption to near zero when not active, extending battery life.
- Through-Hole Package: 8-DIP allows easy breadboarding and manual assembly for DIY projects.
- Low Distortion: Class AB design ensures clean audio reproduction for headphone use.
