ES7149
ES7149是一款低成本的12针立体声数模转换器。ES7149可以接受长达24位字的I2s串行音频数据格式。该装置采用先进的多位△-∑调制技术，将数据转换成双通道模拟输出。多位△-∑调制器使器件对时钟抖动的灵敏度很低，带外噪声也很低
ES7149特性：106dB信噪比-85dB THD+N高达100kHz采样频率支持USB时钟或非标准音频时钟，如25MHz或26MHzI2s音频数据格式，16-24位单电源3V至3.6V
ES7149 GENERAL DESCRIPTION The ES7149 is a low cost 12-pin stereo digital to analog converter. The ES7149 can accept I²S serial audio data format up to 24-bit word length. The device uses advanced multi-bit ∆-∑ modulation technique to convert data into two channel analog outputs. The multi-bit ∆-∑ modulator makes the device with very low sensitivity to clock jitter and very low out of band noise. FEATURES 106 dB SNR -85 dB THD+N Up to 100 kHz sampling frequency Support USB clocks or non standard audio clocks like 25 MHz or 26 MHz I2S audio data format, 16-24 bits Single power supply 3V to 3.6V
