说明

PCM182x 是一款高性能、Burr-Brown™ 音频模数转换器 (ADC),可支持最多两个模拟通道的同步采样。该器件支持差分线路和麦克风输入,具有 2VRMS 满量程信号,集成了锁相环 (PLL) 和直流滤除高通滤波器 (HPF),并支持高达 192kHz 的采样率。该器件支持时分多路复用 (TDM) 或 I2S 音频格式,且硬件引脚电平可选。此外,PCM182x 还支持主从模式选择,从而实现音频总线接口操作。这些集成的高性能特性,以及采用 3.3 V 单电源供电的功能,使该器件非常适用于远场麦克风录音应用中成本敏感、空间受限的音频系统。

PCM182x 的额定工作温度范围为 –40°C 至 +125°C,并且采用 20 引脚 WQFN 封装。
