Overview

Productnnu ICs for Telephone AN6215S AGC IC for telephone speech network s Overview The AN6215S is an AGC IC for telephone speech network, and it incorporates an microphone input detection circuit and a receiver gain control circuit.

It is especially best suited for cordless telephone thanks to a good speech tone quality obtained by reducing howling and echo sound.

Key Features

  • Operation with wide power supply voltage range from 2.1 V to 6.0 V.
  • Enlargement of dynamic range by incorporating a vari- able VREF circuit that varies according to the supply voltage.
  • Possible to adjust the received voice attenuation amount with an external resistor.
  • Possible to adjust the AGC operating point with an external resistor.
  • Possible to design with fewer external components 0.1ae±n0.1dc 1.27e0.6 ± 0.3/ 0.4 ± 0.25 5.0 ± 0.3 lifecycle 0.
