The LTC1195 is a video operational amplifier optimized for
operation on single 5V and 5V supply. 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 6V
unity-gain stable bandwidth of 50MHz, and 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 inte-
grators, 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.
