3159-QFP64E

[LA8515NM]

SANYO : QIP64E

Features

c Because it is possible to switch the Balancing Network

between two systems, one for the near end and one for the

far end, in accordance with the line current, this IC provides

excellent sidetone characteristics over a wide range of line

currents.

c Receiver amplifier supports ceramic receivers and dynamic

receivers.

c Power amplifier on chip

(VCC = 5 V, RL = 8 â¦, PO = 200 mW).

c Crosspoint switches allow full mixing, permitting the

implementation of a variety of functions, such as three- or

four-way calls.

c Digital volume control on chip (power system output).
