LT1191 Ultrahigh Speed Operational Amplifier UFEATURESDESCRIPTIO ■ Gain Bandwidth Product, AV = 1: 90MHz The LT®1191 is a video operational amplifier optimized for ■ Slew Rate: 450V/µs operation on ±5V and a single 5V supply. Unlike many high ■ Low Cost speed amplifiers, this amplifier features high open-loop ■ Output Current: ±50mA gain, over 90dB, and the ability to drive heavy loads to a ■ Settling Time: 110ns to 0.1% full-power bandwidth of 20MHz at 7VP-P. In addition to its ■ Differential Gain Error: 0.07%, (RL = 1k) very fast slew rate, the LT1191 features a unity-gain-stable ■ Differential Phase Error: 0.02°, (RL = 1k) bandwidth of 90MHz. ■ High Open-Loop Gain: 20V/mV Min Because the LT1191 is a true operational amplifier, it is an ■ Single Supply 5V Operation ideal choice for wideband signal conditioning, fast inte- ■ Output Shutdown grators, active filters, and applications requiring speed, U accuracy and low cost. APPLICATIO S The LT1191 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 , LTC and LT are registered trademarks of Linear Technology Corporation. ■ D/A Current to Voltage Conversion UTYPICAL APPLICATIOVideo MUX Cable Driver 5V 7 3 VIN1 + 6 LT1191 Inverter Pulse Response 2 SHDN – CMOS IN 5 CH.
