Note 4:
Differential gain and phase are measured using a Tektronix
TSG120YC/NTSC signal generator and a Tektronix 1780R Video
Measurement Set. The resolution of this equipment is 0.1% and 0.1
°
. Five
identical amplifier stages were cascaded giving an effective resolution of
0.02% and 0.02
°
.
Note 5:
Differential gain and phase are best when the control is set at 0%
or 100%. See the Typical Performance Characteristics curves.
Note 6:
Tested with R
L
= 150
to 2.5V to simulate an AC coupled load.
Note 7:
Small-signal control path response is measured driving R
C
(Pin 5)
to eliminate peaking caused by stray capacitance on Pin 4.
