双通道语音频带编解码器

AD73322和AD73322L均为双通道前端处理器，适合包括语音和电话在内的一般应用。这些器件配有两个16位模数转换通道和两个16位数模转换通道，各通道在语音频带信号带宽上均可实现77 dB的信噪比。AD73322可以采用3 V和5 V电源供电，AD73322L则只能采用3 V电源供电。此外，这些器件的模拟域和数字域均提供输入至输出增益网络。两款编解码器均提供这种网络；与用户线路接口电路(SLIC)接口时，可以利用这些网络实现阻抗匹配或缩放。\n\n模数和数模转换通道的可编程输入/输出增益范围分别为38 dB和21 dB。同时片内集成基准电压源，支持单电源工作。通过编程设置该基准电压，可以支 •16位模数转换器\n\n• 16位数模转换器\n\n• 可编程输入/输出采样速率\n\n• ADC信噪比：75 dB\n\n• DAC信噪比：70 dB\n\n• 最大采样速率：64 ksps;
