LM4935 Features

* a bi-directional I2S serial interface for full range audio and an I2C or SPI compatible interface for control. The stereo DAC path features an SNR of 88 dB with an 18-bit 48 kHz input. In SE mode the headphone amplifier delivers at least 33 mWRMS to a 32Ω single-ended stereo load with less than 1% d
