Technical content

The AN6167S and AN6167SB are speech network ICs for the handset of a cordless telephone. They incorporate compan- der, MIC, and receiver amplifiers. With a minimal number of external components, they can perform all the functions of the handset of a cordless telephone featuring low radio-transmis- sion noise. n Features

  • The compressor/expander circuit incorporates preamplifiers to make level and frequency adjustments easier.
  • The standby circuit provides for a low-power consumption cordless telephone.
  • The expander has a 6-dB amplifier to allow received-signal amplificaition.
  • SOP package with 1.27mm pitch pins, and USO package with 0.8mm pitch pins.
