STMicroelectronics TS488
The TS488 is a dual audio power amplifier capable of driving, in single-ended mode, either a 16 Ω or a 32 Ω stereo headset. The TS488 eliminates pop and click noise and reduces the number of required external passive components. The unity gain stable is configured by external gain-setting resistors.| Part No. | TS488 |

DESCRIPTION
Capable of descending to low voltages, it delivers up to 31 mW per channel (into 16 Ω loads) of continuous average power with 0.1% THD+N in the audio bandwidth from a 2.5 V power supply. An externally-controlled standby mode reduces the supply current to 10 nA (typ.). DS4579 - Rev 8 - May 2020 For further information contact your local STMicroelectronics sales office.
