Description

The ALC5640-VB is a high performance, low power, dual I2S interface audio CODEC. Dual I2S interface can connect to different devices and let the ALC5640 to be an Audio Hub. Each device can pass through the Audio Hub and then perform as input or output application. Asynchronous Sample Rate Converter (ASRC) provides independent and asynchronous connections to different processors, such as an application processor, baseband processor or wireless transceiver(BT). Stereo Class-D speaker amplifiers provide 1.5W per channel into 8Ω or 2.5W per channel into 4Ω with a 5V supply, with excellent PSRR and low EMI. A mono differential earpiece amplifier is also provided, providing output from any DAC or Analog-in. The ALC5640 features an ultra low power cap-free headphone amplifier. It consumes only less than 5mW power
