LT1190 Ultrahigh Speed Operational Amplifier FEATURES DESCRIPTIO n Gain Bandwidth Product, A = 1: 50MHz The LT 1190 is a video operational amplifier optimized for V n Slew Rate: 450V/m s operation on 5V, and a single 5V supply. Unlike many n Low Cost high speed amplifiers, this amplifier features high open- n Output Current: 50mA loop gain, over 85dB, and the ability to drive heavy loads n Settling Time: 140ns to 0.1% to a full-power bandwidth of 20MHz at 7V . In addition P-P n Differential Gain Error: 0.1%, (R = 1k) to its very fast slew rate, the LT1190 features a unity- L n Differential Phase Error: 0.06 , (R = 1k) gain-stable bandwidth of 50MHz and a 75 phase margin, L n High Open-Loop Gain: 10V/mV Min making it extremely easy to use. n Single Supply 5V Operation Because the LT1190 is a true operational amplifier, it is an n Output Shutdown ideal choice for wideband signal conditioning, fast inte- grators, active filters, and applications requiring speed, U accuracy and low cost. APPLICATIO S The LT1190 is available in 8-pin PDIP and SO packages n Video Cable Drivers with standard pinouts. The normally unused Pin 5 is used n Video Signal Processing for a shutdown feature that shuts off the output and n Fast Integrators reduces power dissipation to a mere 15mW. n Pulse Amplifiers n D/A Current to Voltage Conversion , LTC and LT are registered trademarks of Linear Technology Corporation.
