Application Information
As R
SET
is increased, I
SET
and the standby power decrease
while the BW/SR also decrease.
Operating at a +5V single supply, the CA3440 exhibits the
following characteristics:
The CA3440 is pin compatible with the 741 except that pins
1 and 5 (typical negative nulling pins) must be connected
either directly to pin 4 or to a negative nulling potentiometer.
In addition, pin 8, the I
SET
terminal, must be returned to
either ground or -V via R
SET
.
