Description

The LT1189’s high slew rate, 220V/µs, wide bandwidth, 35MHz, and ±20mA output current require only 13mA of supply current. The shutdown feature reduces the power dissipation to a mere 15mW, and allows multiple 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 mini DIPs and SO packages. For lower gain applications see the LT1187 data sheet.
