Features
Excellent common-mode rejection ratio (CMRR),
>40 dB
Supplied 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
3.3 or 5.0 Volt operation
High differential input impedance, very low common-
mode input impedance
Fixed gain
Differential or single-ended linear output
TTL logic input
CMOS logic output (TTL compatible)
Virtually non-detectable in voice monitoring
applications
Applications
In signal monitoring applications, CPC5710N can be
used for:
Display feature (caller ID) signal processing
Line-in-use detection (another-phone-off-hook)
Ringing signal level detection
Battery presence monitoring
Tip and ring lead voltage monitoring
Line condition detection, including line polarity, tip
and ring lead voltage, and battery presence
Description
The Clare CPC5710N is a CMOS special purpose
fixed-gain amplifier with comparator for telephone line
monitoring. The high (>40 dB) common-mode
rejection ratio makes the CPC5710N an excellent
choice for signal monitoring, discrete voice recording,
and line condition monitoring applications. The
CPC5710N is ideal for modem applications including
embedded modem designs like set-top boxes, and
voice recording applications.
