LT1207 Dual 250mA/60MHz Current Feedback Amplifier UFEATUSREDESCRIPTIO ■ 250mA Minimum Output Drive Current The LT ®1207 is a dual version of the LT1206 high speed ■ 60MHz Bandwidth, AV = 2, RL = 100Ω current feedback amplifier. Like the LT1206, each CFA in ■ 900V/µs Slew Rate, AV = 2, RL = 50Ω the dual has excellent video characteristics: 60MHz band- ■ 0.02% Differential Gain, AV = 2, RL = 30Ω width, 250mA minimum output drive current, 400V/µs ■ 0.17° Differential Phase, AV = 2, RL = 30Ω minimum slew rate, low differential gain (0.02% typ) and ■ High Input Impedance: 10MΩ low differential phase (0.17° typ). The LT1207 includes a ■ Shutdown Mode: IS < 200µA per Amplifier pin for an optional compensation network which stabi- ■ Stable with CL = 10,000pF lizes the amplifier for heavy capacitive loads. Both ampli- U fiers have thermal and current limit circuits which protect APPLICATIO S against fault conditions. These capabilities make the LT1207 ■ ADSL/HDSL Drivers well suited for driving difficult loads such as cables in video ■ Video Amplifiers or digital communication systems. ■ Cable Drivers Operation is fully specified from ±5V to ±15V supplies. ■ RGB Amplifiers Supply current is typically 20mA per amplifier. Two ■ Test Equipment Amplifiers micropower shutdown controls place each amplifier in a ■ Buffers high impedance low current mode, dropping supply current to 200µA per amplifier. For reduced bandwidth applications, supply current can be lowered by adding a resistor in series with the Shutdown pin. The LT1207 is manufactured on Linear Technology's complementary bipolar process and is available in a low thermal resistance 16-lead SO package. , LTC and LT are registered trademarks of Linear Technology Corporation.
