Note 1:
A heat sink may be required to keep the junction temperature
below absolute maximum when the output is shorted indefinitely.

Note 1:
Differential Gain and Phase are measured using a Tektronix TSG
120 YC/NTSC signal generator and a Tektronix 1780R Video Measurement
Set. The resolution of this equipment is 0.1% and 0.1°. Ten identical
U W
amplifier stages were cascaded giving an effective resolution of 0.01% and
0.01°.
