DESCRIPTIO
The LT^®1190 is a video operational amplifier optimized for
operation on ±5V, and a single 5V supply. Unlike many
high speed amplifiers, this amplifier features high open-
loop gain, over 85dB, and the ability to drive heavy loads
to a full-power bandwidth of 20MHz at 7V_P-P. In addition
to its very fast slew rate, the LT1190 features a unity-
gain-stable bandwidth of 50MHz and a 75° phase margin,
making it extremely easy to use.
Because the LT1190 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 LT1190 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.
