FSA8008A Audio Jack Detection and Configuration Switch The FSA8008A is an audio jack detector and switch for 3− or 4−pole accessories. In addition to detection, the FSA8008A features an integrated MIC switch that allows the processor to configure the audio jack. The architecture is designed to allow common third−party headphones to be used for listening to music from mobile handsets, personal media players, and portable peripheral devices. www.onsemi.com Features • Determines 3− or 4−Pole Audio Jacks • Removes Audio Jack Pop−n−Click Caused by MIC Bias • Detects Audio Jack Accessories: 1 UQFN10 CASE 523BC ♦ Standard Headphones ♦ Headsets with MIC ♦ Send / End Button Presses Integrates a MIC Switch for 4−Pole Configuration Detection Accessory Plug−In 3− or 4−Pole Audio Jack Send/End Key Pressed Functionality Decreased Timing for Sensitive Send/End Keys • 3.5 mm and 2.5 mm Audio Jacks • Cellular Phones, Smartphones • MP3 and PMP Switch Type MIC VDD 2.5 to 4.4 V VIO 1.6 to VDD THD (MIC) 0.01% Typical Related Resources ESD (Air Gap) 15 kV Operating Temperature −40°C to 85°C Package 10−Lead UMLP 1.4 x 1.8 x 0.5 mm, 0.4 mm Pitch Top Mark KD Ordering Information FSA8008AUMX • Applications • FSA8008A Demonstration Board 2.5 to 4.4V Baseband Processor 1.6 to VDD VDD VIO VDD DET EN J POLE S/E GPIO 1 GPIO 2 GPIO 3 GPIO 4 LOW = plugged HIGH = unplugged Normally Open (NO ) Switch 0.5mA J _DET L R GND MIC Oscillator and Logic 1 2 3 4 Audio R MIC MIC MIC Bias 16−32W COMP CMIC HIGH =>J_MIC=0V LOW =>J_MIC>0.2V R SPKR GND 16−32W MIC L SPKR J_MIC S − Figure 1.
