Notes on Operation
1) This IC is a wideband amplifier with wide gain control range. The decouping capacitors between GND Pin
and V
CC
Pin should be as close to the IC as possible.
2) The resistors connected to Pins 9 and 10 should be as close to the IC as possible.
3) This IC assumes the excellent characteristics when the differential input impedance between Pins 1 and 2
is 500
. Refer to the Measurement Circuit for the external element settings, etc.
4) Pay attention to handling this IC because its electrostatic discharge strength is weak.
