onsemi LC70310KBG
The LC70310KBG is a noise-cancellation IC that uses an original digital signal processor (DSP) designed for audio applications as the core and integrates the serial PCM interface and host CPU interface on a single chip. The LC70310KBG also makes it possible to provide filter processing and other such operations alongside the noisecancelling function. The PCM interface supports the I2S mode and enables stereo sound processing.| Part No. | LC70310KBG |
