Product Description

DESCRIPTION
The LT®1227 is a current feedback amplifier with wide bandwidth and excellent video characteristics. The low differential gain and phase, wide bandwidth, and 30mA output drive current make the LT1227 well suited to drive cables in video systems.
A shutdown feature switches the device into a high impedance, low current mode, allowing multiple devices to be connected in parallel and selected. Input to output isolation in shutdown is 70dB at 10MHz for input amplitudes up to 10VP-P. The shutdown pin interfaces to open collector or open drain logic and takes only 4µs to enable or disable.
FEATURES
■ 140MHz Bandwidth: AV = 2, RL = 150Ω
■ 1100V/µs Slew Rate
■ Low Cost
■ 30mA Output Drive Current
■ 0.01% Differential Gain
■ 0.01° Differential Phase
■ High Input Impedance: 14MΩ, 3pF
■ Wide Supply Range: ±2V to ±15V
■ Shutdown Mode: IS < 250µA
■ Low Supply Current: IS = 10mA
■ Inputs Common Mode to Within 1.5V of Supplies
■ Outputs Swing Within 0.8V of Supplies
APPLICATIONS
■ Video Amplifiers
■ Cable Drivers
■ RGB Amplifiers
■ Test Equipment Amplifiers
■ 50Ω Buffers for Driving Mixers
