FEATURES  
DESCRIPTION  
The LT®1497 dual current feedback amplifier features low  
power, high output drive, excellent video characteristics  
and outstanding distortion performance. From a low 7mA  
maximum supply current per amplifier, the LT1497 drives  
±100mAwithonly1.9Vofheadroom.Twistedpairscanbe  
drivendifferentiallywith 70dBcdistortionupto1MHzfor  
±40mA peak signals.  
Minimum Output Current:  
±
125mA  
Maximum Supply Current per Amp: 7mA, 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 = 100mA, VS = ±15V  
±3.1V Output Swing: IL = 100mA, VS = ±5V  
55ns Settling Time to 0.1%, 10V Step  
Thermal Shutdown Protection  
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  
complementary bipolar process. The device has charac-  
teristics that bridge the performance between the LT1229  
and LT1207 dual current feedback amplifiers. The LT1229  
has 30mA output drive, 100MHz bandwidth and 12mA  
supply current. The LT1207 has 250mA output drive,  
60MHz bandwidth and 40mA supply current.
