lm7121imx National Semiconductor Corporation, lm7121imx Datasheet - Page 15

• Manufacturer Part Number: lm7121imx
• Description: 235 Mhz Tiny Low Power Voltage Feedback Amplifier
• Manufacturer: National Semiconductor Corporation

Application Information
It is very important to keep the lead lengths to a minimum
and to provide a low impedance current path by using a
ground-plane on the board.
Caution: If R
of LM7121 would be disturbed and it would have to supply
the full amount of load current. This might damage the part if
power dissipation limit is exceeded.
L
is removed, the current balance at the output

The circuit shown in Figure 4 can be used to drive in excess
of 25 meters length of twisted pair cable with no loss of reso-
lution or picture definition when driving a NTSC monitor at
the load end.
