Brand: Aplus Integrated Circuits · SKU: P489K · MPN: AP4890K · Category: Components
The AP4890K is a 1.4 Watt audio power amplifier primarily designed for high-quality applications in portable communication devices. It is capable of driving an 8Ω speaker load at a continuous average output of 1.4W with 10% distortion (THD+N) from a 5.0V power supply. A key feature is the ability to switch to BTL mode. The amplifier includes a low power consumption shutdown mode (activated by driving the shutdown pin with logic high) and internal thermal shutdown protection. It is designed to provide high-quality output power with minimal external components, as it does not require output capacitors or bootstrap capacitors, making it ideal for low voltage and portable electronic devices where minimal power consumption is crucial. Applications include portable electronic devices, mobile phones, and PDAs.
