一般说明：MAX9860ETG+T
MAX9860ETG+T是低功耗，语音频带，单声道音频旨在提供完整音频解决方案的编解码器用于无线语音耳机和其他单声道语音音频设备。使用片上桥接负载单声道耳机放大器，MAX9860ETG+T可将30mW的功率输出到32Ω耳机，同时使用1.8V单电源供电供应。极低的功耗使其成为理想选择电池供电应用的选择。
MAX9860ETG+T的灵活时钟电路利用常见的系统时钟频率，范围为10MHz至60MHz，无需外部PLL和多个晶体振荡器。 ADC和DAC在同步或异步操作中均支持8kHz至48kHz的采样率。主从支持计时模式。两个差分麦克风输入可与用户可编程的前置放大器和可编程的增益放大器。可选的自动增益控制攻击/释放时间和信号阈值允许最大动态范围。可选的噪声门阈值可在以下情况下使通道静音没有信号。 DAC和ADC数字滤波器为带外信号以及5阶GSM兼容数字高通滤波器。数字侧音混音器可将麦克风/ ADC信号环回至DAC /耳机输出。串行DAC和ADC数据通过灵活的传输方式与I2S兼容的数字接口也支持TDM模式。模式设置，音量控制和关机通过2线I2C兼容接口进行编程。
MAX9860ETG+T的额定温度范围为-40°C至+ 85°C扩展了温度范围，并采用扁平的4mm x 4mm，24引脚薄型QFN封装。
