Summary
Excellent common-mode rejection ratio (CMRR)
Description
The CPC5710N is a selectable dual function CMOS special purpose integrated high-impedance input, fixed-gain amplifier and an internally set voltage level comparator for telephone line monitoring. The high (>40dB) common-mode rejection ratio makes the CPC5710N an excellent choice for signaling detection, line condition monitoring, discrete voice recording and CID buffering applications. In addition to voice applications, the CPC5710N is ideal for data applications such as embedded modem designs utilized in broadband set-top boxes.
