ADAU1361 is a 24-bit stereo audio ADC and DAC with features such as low power consumption, flexible analog input/output mixer, microphone bias voltage, etc.
The Analog Devices ADAU1361 is a low-power, stereo audio codec designed for battery-powered audio and telephone applications. It features a 24-bit stereo audio ADC and DAC with a sampling rate range of 8 kHz to 96 kHz. The device supports digital volume control and includes six analog input pins that can be configured for single-ended or differential inputs. It also features stereo digital microphone input and multiple output drivers for stereo headphones, hands-free, or other output sensors.
The ADAU1361 integrates an internal PLL supporting input clock frequencies from 8 MHz to 27 MHz, allowing for flexible generation of standard integer multiple clock frequencies and fractional master clock frequencies. The codec supports I2C and SPI control interfaces and offers software-controllable noiseless mute and power-down modes. It is available in a 32-pin, 5 mm x 5 mm LFCSP package with an operating temperature range of -40°C to +85°C. This manual is written in Chinese.
