Notes:

*1 VCC power supply pins 1, 13, 23 and 28 are connected to each other externally.

*2 Measure offset voltage between any two amps.

*3 Measure gain difference between any two amps. VIN=1VP-P

*4 Measure attenuation amount relative to Av max., and quantify the difference between any two amps.

*5 The voltage at which V12 low is -40dB relative to AV max. for attenuation.

*6 Mount on printed board with ground shield on both sides.

*7 -3dB cutoff frequency from video amp gain.

*8 Input a signal to any amp and terminate input for the remaining two amps (use resistor that corresponds

to signal source load), then measure output.

*9 Human model. Discharge via 1.5kΩ from 100pF capacitor.

*10 Solder for 10 seconds.
