Texas Instruments PCM512x / PCM514x音频立体声数模转换器
德州仪器PCM512x和PCM514x音频立体声数模转换器是单片CMOS集成电路系列产品,它在一个薄型小外形尺寸(TSSOP) 封装内包含了一个附加支持电路。PCM512x和PCM514x使用德州仪器最新的高级分段数模转换器架构,实现了优异的动态性能,并提升了对于时钟抖动的耐受度。PCM514x系列产品集成了一个完全可编程的miniDSP 内核,使开发人员能将滤波器、动态范围控制、定制内插器和其它差分特性集成进他们的产品中。PCM512x系列产品成员将预置音频处理功能与可编程系数相集成,使开发人员能改变产品内的内插滤波器、扬声器EQ、动态范围控制以及平均音量控制的特征。特性
