characteristics better than many voltage feedback ampli-

fiers.Thisversatileamplifierisfast,280nssettlingto0.1%

for a 10V step thanks to its 500V/µs 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 350µA.

The LT1217 is excellent for driving cables and other low

impedance loads thanks to a minimum output drive cur-

rentof50mA.Operatingonanysuppliesfrom±5Vto±15V

allows the LT1217 to be used in almost any system. Like

other current feedback amplifiers, the LT1217 has high
