一.产品概述Nrp嘉泰姆

    The CXAS4232B is an audio jack detection switch for CITA and OMTP 4-pole accessories. The pin MIC is on audio key side, as CXAS4232B' O1/O2 is plugged into audio jack of cell phone, it will detect the locations of ground (GND) and microphone (MIC) poles on the audio plug and automatically routes them to the appropriate connections. Nrp嘉泰姆

   The MIC switch' Ron is 5 Ω (typical) while the Ground switch has a low Ron of 0.5 Ω (typical) to minimize voltage drop across it, preventing undesired increase in ground reference voltage. Nrp嘉泰姆

   As VCC is power-up, CXAS4232B is enabled and it consumes ultra-low quiescent current, less than 600nA (typical). The range of signal swing in transmission can be rail-to-rail (0~VCC), even CXAS4232B can tolerate signal swing higher than VCC but less than VCC+3V with very little inverse leakage into VCC supply and not any damage of the device. The speed of signal is recommended not more than 300KHz. Nrp嘉泰姆

   The CXAS4232B is available in SOT-353 package. Standard product is Pb-Free and halogen-Free.  Nrp嘉泰姆
