The CPC5710NTR is a part of CPC Series 5 V 40 dB Surface mount Phone Line Monitor IC available in a SOIC-8 package.

It 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.

Product Features:

  • 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
  • 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


  • Display feature (caller ID) signal buffering
  • Line-In-Use (LIU) detection
  • inging signal with adjustable detection level
  • Battery presence monitoring
  • Tip to ring line voltage monitoring
