SCDS346A –JUNE 2013–REVISED JULY 2013

Autonomous Audio Headset Switch with Reduced GND Switch R and FM Capability

Check for Samples: TS3A226AE

FEATURES

DESCRIPTION

The TS3A226AE is an audio headset switch that

detects 3- or 4-pole 3.5mm accessories. For a 4-pole

accessory with a microphone, the TS3A226AE also

detects the MIC location and routes the microphone

and ground signals automatically. The ground signal

is routed through a pair of low-impedance ground

FETs (60mΩ typical), resulting minimal impact on

audio cross-talk performance. The autonomous

detection feature allows end users to plug in

accessories with different audio pole configurations

into the mobile device and have them operate

properly with no added software control and

complexity. The ground FETs of the device are

designed to allow FM signal pass-through, making it

possible to use the ground line of the headset as an

FM antenna in mobile audio application.
