NL3S325 Audio Jack GND/MIC Configuration Switch The NL3S325 is an audio jack configuration switch device. It allows reconfiguration of the GND, microphonebias contact to comply with the American Headset Jack (AHJ) and the Open Mobile www.onsemi.com Terminal Platform (OMTP) pinout. It also provides a GND sense path that supports quasidifferential audio amplifier architectures.
