Analog & Power: Current-Feedback Amplifier Provides High Bandwidth

    With high bandwidth at both low and high gains, the OPA695 low-power, current-feedback amplifier will find homes in video signal processing, cable modems, and test instrumentation. At higher gains (G = +8), the device offers a 4300-V/µs slew rate and greater than 450-MHz bandwidth. Capable of single-supply operation at +5 to +12 V, it offers an improved output intercept at lower power than existing dedicated IF amplifiers. At lower gains (G = +2), bandwidth is 1.4 GHz with a 2500-V/µs slew rate. Prices start at $1.35 each in lots of 1000.
