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.
