LT1217 Low Power 10MHz Current Feedback Amplifier Features s s s s s s s s s DESCRIPTIO 1m A Quiescent Current 50m A Output Current (Minimum) 10MHz Bandwidth 500V/µs Slew Rate 280ns Settling Time to 0.1% Wide Supply Range, ±5V to ±15V 1m V Input Offset Voltage 100n A Input Bias Current 100MΩ Input Resistance The LT1217 is a 10MHz current feedback amplifier with DC characteristics better than many voltage feedback amplifiers. This versatile amplifier is fast, 280ns settling to 0.1% for a 10V step thanks to its 500V/µs slew rate. The LT1217 is manufactured on Linear Technology’s proprietary plementary bipolar process resulting in a low 1m A 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 current of 50m A. Operating on any supplies from ± 5V to ±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 es in the industry standard pinout and can upgrade the performance of many older products.
