LT1497 Dual 125m A, 50MHz Current Feedback Amplifier Features s s s s s DESCRIPTION The LT®1497 dual current feedback amplifier Features low power, high output drive, excellent video characteristics and outstanding distortion performance. From a low 7m A maximum supply current per amplifier, the LT1497 drives ± 100m A with only 1.9V of headroom. Twisted pairs can be driven differentially with - 70d Bc distortion up to 1MHz for ± 40m A peak signals. The LT1497 is available in a low thermal resistance 16-pin SO package for operation with supplies up to ± 15V. For ± 5V operation the device is also available in a low thermal resistance SO-8 package. The device has thermal and current limit circuits that protect against fault conditions. The LT1497 is manufactured on Linear Technology’s plementary bipolar process. The device has characteristics that bridge the performance between the LT1229 and LT1207 dual current feedback amplifiers. The LT1229 has 30m A output drive, 100MHz bandwidth and 12m A supply current. The LT1207 has 250m A output drive, 60MHz bandwidth and 40m A supply current. , LTC and LT are registered trademarks of Linear Technology Corporation. s s s s s s s Minimum Output Current: ±125m A Maximum Supply Current per Amp: 7m A, VS = ±5V Bandwidth: 50MHz, VS = ± 15V Slew Rate: 900V/µs, VS = ± 15V Wide Supply Range: VS = ± 2.5V to ± 15V (Enhanced θJA 16-Pin SO Package) Enhanced θJA SO-8 Package for ± 5V Operation 0.02% Differential Gain: AV = 2, RL = 150Ω 0.015° Differential Phase: AV = 2, RL = 150Ω ± 13V Output Swing: IL = 100m A, VS = ± 15V ± 3.1V Output Swing: IL = 100m A, VS = ± 5V 55ns Settling Time to 0.1%, 10V Step Thermal Shutdown Protection U APPLICATIONS s s s s s Twisted-Pair Drivers Video Amplifiers Cable Drivers Test Equipment Amplifiers Buffers TYPICAL APPLICATION HDSL2 Single Pair Line Driver 560Ω 560Ω - 40 2nd and 3rd Harmonic Distortion of HDSL2 Single Pair Line Driver VS = ± 5V VIN = ± 1.25V VOUT = ± 2.5V - 68.1Ω - 50 + DISTORTION (d...
