... The shutdown feature reduces the power dissipation to a mere 15mW, and allows multiple amplifi- ers to drive the same cable. The LT1187 is a low power version of the popular LT1193, and is available in 8-pin miniDIPs and SO packages. For applications with gains more, see the LT1189 data sheet ...

... LT1187 U U APPLICATIO S I FOR ATIO The primary use of the LT1187 is in converting high speed differential signals to a single-ended output. The LT1187 video difference amplifier has two uncommitted high input impedance (+) and (–) inputs. The amplifier has another set of inputs which can be used for reference and feed- back ...

... WITH 8pF FEEDBACK CAPACITOR V Extending the Input Range Figure 1 shows a simplified schematic of the LT1187. In normal operation the REF pin 1 is grounded or taken offset control voltage and differential signals are ap- plied between pins 2 and 3. The input responds linearly 100M until all of the 345 A current flows through the 1.1k LT1187 • ...
