DESCRIPTIO
The LT
operation on 5V and a single 5V supply. Unlike many high
speed amplifiers, this amplifier features high open-loop
gain, over 90dB, and the ability to drive heavy loads to a
full-power bandwidth of 20MHz at 7V
very fast slew rate, the LT1191 features a unity-gain-stable
bandwidth of 90MHz.
Because the LT1191 is a true operational amplifier, it is an
ideal choice for wideband signal conditioning, fast inte-
grators, active filters, and applications requiring speed,
accuracy and low cost.
The LT1191 is available in 8-pin PDIP and SO packages
with standard pinouts. The normally unused Pin 5 is used
for a shutdown feature that shuts off the output and
reduces power dissipation to a mere 15mW.
