ST75951 数据手册 ( 数据表 ) - STMicroelectronics

DESCRIPTION
ST75951 is an analog front-end designed to implement modems application up to 56Kbps.
ST75951 interfaces between DSP or HSP signals and capacitive isolation barrier.
A complete D.A.A. is made with ST952 which interfaces between capacitive isolation barrier and the telephone line.
It integrates a high resolution A/D and D/A converter and incorporates Krypton Isolation Inc. patented silicon D.A.A. technology.
