Typical Application
Description
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 7VP-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 integrators, 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.
