DESCRIPTIO
The LT®1195 is a video operational amplifier optimized for
operation on single 5V and ±5V supplies. Unlike many
high speed amplifiers, the LT1195 features high open-
loop gain, over 75dB, and the ability to drive heavy loads
to a full power bandwidth of 8.5 MHz at 6VP-P. The LT1195
has a unity-gain stable bandwidth of 50MHz, a 60° phase
margin and consumes only 12mA of supply current,
making it extremely easy to use.
Because the LT1195 is a true operational amplifier, it is an
ideal choice for wideband signal conditioning, fast
integrators, peak detectors, active filters, and applications
requiring speed, accuracy, and low cost.
The LT1195 is a low power version of the popular LT1190,
and is available in 8-pin miniDIPs 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.
