LT1190 Ultrahigh Speed Operational Amplifier
U FEATURES DESCRIPTIO
■ Gain Bandwidth Product, AV = 1: 50MHz The LT®1190 is a video operational amplifier optimized for ■ Slew Rate: 450V/µs operation on ±5V, and a single 5V supply. Unlike many ■ Low Cost high speed amplifiers, this amplifier features high open- ■ Output Current: ±50mA loop gain, over 85dB, and the ability to drive heavy loads ■ Settling Time: 140ns to 0.1% to a full-power bandwidth of 20MHz at 7VP-P. In addition ■ Differential Gain Error: 0.1%, (RL = 1k) to its very fast slew rate, the LT1190 features a unity- ■ Differential Phase Error: 0.06°, (RL = 1k) gain-stable bandwidth of 50MHz and a 75° phase margin, ■ High Open-Loop Gain: 10V/mV Min making it extremely easy to use. ■ Single Supply 5V Operation Because the LT1190 is a true operational amplifier, it is an ■ Output Shutdown ideal choice for wideband signal conditioning, fast inte-

accuracy and low cost. The LT1190 is available in 8-pin PDIP and SO packages ■ Video Cable Drivers with standard pinouts. The normally unused Pin 5 is used ■ Video Signal Processing for a shutdown feature that shuts off the output and ■ Fast Integrators reduces power dissipation to a mere 15mW. ■ Pulse Amplifiers ■ D/A Current to Voltage Conversion , LTC and LT are registered trademarks of Linear Technology Corporation.
