LT1497

Dual 125mA, 50MHz

Current Feedback Amplifier

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, V_S= ±5V

■

Bandwidth: 50MHz, V_S= ±15V

Slew Rate: 900V/µs, V_S= ±15V

Wide Supply Range: V_S= ±2.5V to ±15V

(Enhanced θ_JA16-Pin SO Package)

Enhanced θ_JASO-8 Package for ±5V Operation

0.02% Differential Gain: A_V= 2, R_L= 150Ω

0.015° Differential Phase: A_V= 2, R_L= 150Ω

±13V Output Swing: I_L= 100mA, V_S= ±15V

±3.1V Output Swing: I_L= 100mA, V_S= ±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.
