“For this prototype I decided to stay with plain old through-hole packages and build the analog part in a modular way. The restriction to through-hole packages had a great influence of what parts I could use because most of the …
Content for LT1227
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 10VP-P. The shutdown pin interfaces to open collector or open drain logic and takes only 4mµ to enable or disable.
