LT1194 Video Difference Amplifier
U FEATURES DESCRIPTIO
■ Differential or Single-Ended Gain Block: ±10 (20dB) The LT®1194 is a video difference amplifier optimized for ■ – 3dB Bandwidth: 35MHz operation on ±5V and a single 5V supply. The amplifier has ■ Slew Rate: 500V/µs a fixed gain of 20dB and features adjustable input limiting ■ Low Cost to control tough overdrive applications. It has uncommit- ■ Output Current: ±50mA ted high input impedance (+) and (–) inputs, and can be ■ Settling Time: 200ns to 0.1% used in differential or single-ended configurations. ■ CMRR at 10MHz: 45dB The LT1194’s high slew rate 500V/µs, wide bandwidth ■ Differential Gain Error: 0.2% 35MHz, and ±50mA output current make it ideal for ■ Differential Phase Error: 0.08° driving cables directly. This versatile amplifier is easy to ■ Input Amplitude Limiting use for video or applications requiring speed, accuracy ■ Single 5V Operation and low cost. ■ Drives Cables Directly The LT1194 is available in 8-pin PDIP and SO packages.
