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 imped-
ance, low current mode, allowing multiple devices to be
connected in parallel and selected. Input to output isola-
tion 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 4
s 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.
