The LT1217 is a 10MHz current feedback amplifier with DC
characteristics better than many voltage feedback ampli-
fiers. This versatile amplifier is fast, 280ns settling to 0.1%
for a 10V step thanks to its 500V/
s slew rate. The LT1217
is manufactured on Linear Technology’s proprietary
complementary bipolar process resulting in a low 1mA
quiescent current. To reduce power dissipation further,
the LT1217 can be turned off, eliminating the load current
and dropping the supply current to 350
A.
The LT1217 is excellent for driving cables and other low
impedance loads thanks to a minimum output drive cur-
rent of 50mA. Operating on any supplies from
±5Vto ±15V
allows the LT1217 to be used in almost any system. Like
other current feedback amplifiers, the LT1217 has high
gain bandwidth at high gains. The bandwidth is over 1MHz
at a gain of 100.
The LT1217 comes in the industry standard pinout and
can upgrade the performance of many older products.
