AN6215S

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. s 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 0.15 0.65 stage.
