不确定(小批量网上购买的,对方称代理分销其网站:http://ti-hlsw.com/),料盘上标PCM2912AE4PJTR,规格:1000,产地TAIWAN
这芯片丝印的在网上也有卖,比PCM2912A便宜不少。
如果是假冒的,那小批量购买能推荐其代理商吗?谢谢
您可以看下PCM2912Adatasheet Page29的package information中有PCM2012A的两种后缀,PCM2912APJT和PCM2912APJTR两种:
而目前PCM2912这款为NRND状态,但是这款的后缀也没有PCM2912AE4PJTR这个后缀,因为目前还没停产,所以在产品主页上还是能查到相关信息的:www.ti.com/.../pinout-quality
