LT1195 Low Power, High Speed Operational Amplifier FEATURES DESCRIPTIO Gain-Bandwidth Product: 50MHz The LT 1195 is a video operational amplifier optimized for Unity-Gain Stable operation on single 5V and 5V supplies. Unlike many Slew Rate: 165V/s high speed amplifiers, the LT1195 features high open- Output Current: 20mA loop gain, over 75dB, and the ability to drive heavy loads Low Supply Current: 12mA to a full power bandwidth of 8.5 MHz at 6V . The LT1195 P-P High Open-Loop Gain: 7.5V/mV has a unity-gain stable bandwidth of 50MHz, a 60 phase Low Cost margin and consumes only 12mA of supply current, Single Supply 5V Operation making it extremely easy to use. Industry Standard Pinout Because the LT1195 is a true operational amplifier, it is an Output Shutdown ideal choice for wideband signal conditioning, fast integrators, peak detectors, active filters, and applications U requiring speed, accuracy, and low cost. APPLICATIO S The LT1195 is a low power version of the popular LT1190, Video Cable Drivers and is available in 8-pin miniDIPs and SO packages with Video Signal Processing standard pinouts. The normally unused Pin 5 is used for a Fast Peak Detectors shutdown feature that shuts off the output and reduces Fast Integrators power dissipation to a mere 15mW.
