The TS3A226AE from Texas Instruments is an autonomous audio headset switch that intelligently detects 3- or 4-pole 3.5mm accessories. It automatically routes microphone and ground signals, simplifying integration into mobile devices without requiring additional software control. This device features low-impedance ground FETs with a typical Ron of 60mΩ, minimizing impact on audio crosstalk performance.
The TS3A226AE supports FM signal transmission through its ground FETs, enabling the headset's ground line to function as an FM antenna. It operates within a VDD range of 2.6V to 4.7V and exhibits a low typical supply current of 6.5µA. The switch also includes features for reducing click and pop noise. Its compact 1.2mm x 1.2mm WCSP package makes it suitable for space-constrained mobile applications.
Key electrical characteristics include a typical THD (Mic) of 0.002% and ±8kV ESD performance on the SLEEVE and RING2 pins according to IEC 61000-4-2. The device is designed for analog audio protocols and offers a bandwidth of 200 MHz.
