Notes Operation This wideband amplifier with wide gain control range. decouping capacitors between should close possible. resistors connected Pins should close possible. This assumes excellent characteristics when differential input impedance between Pins Pins 500. Refer Measurement Circuit external element settings, etc. attention handling this because electrostatic discharge strength weak.
