LT1252 Low Cost Video Amplifier
U FEATU S RE DESCRIPTIO
■ Low Cost The LT1252 is a low cost current feedback amplifier for ■ Current Feedback Amplifier video applications. The LT1252 is ideal for driving low ■ Differential Gain: 0.01%, RL = 150Ω, VS = ±5V impedance loads such as cables and filters. The wide ■ Differential Phase: 0.09°, RL = 150Ω, VS = ±5V bandwidth and high slew rate of this amplifier make ■ Flat to 30MHz, 0.1dB driving RGB signals between PCs and workstations easy. ■ 100MHz Bandwidth on ±5V The linearity of the LT1252 is outstanding; it is unsur- ■ Wide Supply Range: ±2V(4V) to ±14V(28V) passed for driving composite video. ■ Low Power: 85mW at ±5V The LT1252 is available in the 8-pin DIP and the S8 surface
