TS3A226AE Datasheet Autonomous Audio Headset Switch

Manufacturer: Texas Instruments

Overview: www.ti.com TS3A226AE SCDS346A – JUNE 2013 – REVISED JULY 2013 Autonomous Audio Headset Switch with Reduced GND Switch RON and FM Capability Check for Samples:.

General 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.

Key Features

  • 1.
  • Ground FET Switches (60mΩ typical).
  • Autonomous Detection of Headset Types: 3-Poles or 4-Poles (with MIC on SLEEVE or RING2).
  • Microphone Line Switches.
  • Supports FM Signal Transmission Through the Ground FETs.
  • Reduction of Click/Pop Noise.
  • VDD Range: 2.6 V.
  • 4.7 V.
  • THD (Mic): 0.002% Typical.
  • Low Current Consumption: 6.5-µA Typical.
  • ±8kV Contract Discharge (IEC 61000-4-2) ESD Performance on SLEEVE and RING2.
