The TS3A227EYFFR from Texas Instruments is an autonomous audio accessory detection and configuration switch designed for consumer audio applications. This device operates within a supply voltage range of 2.5V to 4.5V and offers a typical on-resistance of 0.05 Ω. It features a bandwidth of 150 MHz, making it suitable for audio signal routing.
The switch supports an I²C interface for control and features autonomous headset MIC/GND detection for 3 or 4 pole accessories. It includes adjustable de-bounce timings, click and pop noise reduction, and power-off noise removal. The device is available in a 16-pin DSBGA package and operates across a temperature range of -40°C to 85°C.
Key functionalities include accessory insertion/removal detection, configuration detection for stereo headphones and headsets with MIC, and key press detection for up to 4 keys. The ultra-low ground FET R ON minimizes crosstalk impact and is designed to pass FM signals. The TS3A227EYFFR also provides isolation of MICBIAS from the audio jack to remove click/pop noise and includes an integrated codec sense line.
