STW5095 Low Power Asynchronous Stereo Audio Codec with Integrated Power Amplifiers

STw5095 is a low power asynchronous stereo audio CODEC device with headphones amplifiers for high quality audio listening and recording. The STw5095 control registers are accessed through a selectable I2C-bus compatible or SPI compatible interface. The supply voltage can be the same for the whole device, in the range 2.4 V to 2.7 V, or it can be differentia.
