... The shutdown feature reduces the power dissipation to a mere 15mW, and allows multiple amplifi- ers to drive the same cable. The LT1189 is a low power, gain of 10 stable version of the popular LT1193, and is available in 8-pin miniDIPs and SO packages. For lower gain applications see the LT1187 data sheet ...

... A PPLICATI S I FOR ATIO The primary use of the LT1189 is in converting high speed differential signals to a single-ended output. The LT1189 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 the LT1189 it is easy to make an instrumentation amplifier that can respond to rapidly varying signals. Attenuation resistors in front of the LT1189 allow very large common-mode signals to be rejected while maintaining good frequency response. The input common-mode and differential-mode ...

... 110 Using the Shutdown Feature The LT1189 has a unique feature that allows the amplifier to be shutdown for conserving power, or for multiplexing LT1189 • AI07 several amplifiers onto a common cable. The amplifier will shutdown by taking pin dissipates 15mW while maintaining a true high impedance output state of about 20k in parallel with the feedback resistors ...
