Features  
Description  
Excellent common-mode rejection ratio (CMRR)  
Application circuits can meet isolation requirements  
of worldwide telephony standards  
Small 8-pin SOIC  
Worldwide telephone network compatibility  
Full-wave ringing level detector comparator with  
internal threshold, large hysteresis, and logic-level  
output  
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.  
3.3V or 5V operation  
High differential input impedance  
Very low common-mode input impedance  
Fixed gain  
Differential or single-ended linear output  
TTL logic level input  
CMOS logic level output (TTL compatible)  
Virtually non-detectable in voice monitoring  
applications
