TS4902 is an audio power amplifier from ON Semiconductor that operates from 2.2V to 5.5V and delivers up to 0.7W of continuous RMS output power into an 8Ω load. It also features an outstanding 0.1% distortion level (THD) from a 5V supply for a Pout of 200mW RMS.
The TS4902 is an audio power amplifier designed to provide a high price-to-power ratio while preserving high audio quality. Operating from a supply voltage (Vcc) of 2.2V to 5.5V, it delivers up to 0.7W of continuous RMS output power into an 8Ω load at 5V. The device features an externally controlled standby mode that reduces supply current to less than 10nA and includes internal thermal shutdown protection.
