Notes on Operation

1) This IC is a wideband amplifier with wide gain control range. The decouping capacitors between GND Pin

and VCC Pin should be as close to the IC as possible.

2) The resistors connected to Pins 5 and 6 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 500Ω. 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.
