FCircuit operation

EVR control characteristic

Gain control is carried out by means of voltage divider be-

tween the GND and the EVR REF pin (pin 2).

FOperation notes

(1) Since muting measures are not taken in the IC

when the power supply is turned on or off, these mea-

sures should be taken externally if necessary.

(2) The gain for the output amplifier should be set to a

value between 0 and 12dB.

(3) DC offset voltage may be produced, depending on

the EVR control point. If this is a problem, insert a cou-

pling capacitor at the point where connection is made to

the next stage.

(4) If DC offset voltage is a problem when switching

modes, countermeasures such as providing a time

constant to the control pin (pin 8) can be taken.
