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