Outputs Swing Within 0.8V of Supplies

The LT1227 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 10V_P-P. The shutdown pin interfaces to open collector or open drain logic and takes only 4mµ to enable or disable.

The LT1227 comes in the industry standard pinout and can upgrade the performance of many older products. For a dual or quad version, see the LT1229/1230 data sheet.

The LT1227 is manufactured on Linear Technology’s proprietary complementary bipolar process.
