The LT1191 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 90dB, and the ability to drive heavy loads to a full-power bandwidth of 20MHz at 7VP-P. In addition to its 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 integrators, 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.
