LT1192 Ultrahigh Speed Operational Amplifier FEATURES DESCRIPTIO n Gain Bandwidth Product, A = 5: 350MHz V The LT1192 is a video operational amplifier optimized for 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 100dB, and the ability to drive heavy loads n Settling Time: 90ns to 0.1% to a full-power bandwidth of 20MHz at 7V . In addition P-P n Differential Gain Error: 0.1% (R = 1k) L to its very fast slew rate, the LT1192 has a high gain n Differential Phase Error: 0.01 (R = 1k) L bandwidth of 350MHz and is compensated for a closed- n High Open-Loop Gain: 100V/mV Min loop gain of 5 or greater. n Single Supply 5V Operation Because the LT1192 is a true operational amplifier, it is an n Output Shutdown ideal choice for wideband signal conditioning, active fil- U ters, and applications requiring speed, accuracy and low APPLICATIO S cost. n Video Cable Drivers The LT1192 is available in 8-pin PDIP and SO packages n Video Signal Processing with standard pinouts. The normally unused Pin 5 is used n Photo Diode Amplifier for a shutdown feature that shuts off the output and n Pulse Amplifiers reduces power dissipation to a mere 15mW. n D/A Current to Voltage Conversion , LTC and LT are registered trademarks of Linear Technology Corporation.
