The CVA4401 delivers a -3dB bandwidth of 400MHz, 150mA, and 11000V/µs while only drawing 5mA of supply current. The CVA4401 operates over a wide supply voltage range of ±5V to ±18V. This product is an excellent choice for driving the video signal from Pre-Amp active load CRT driver.

DC and AC electrical specifications do not apply when operating the device beyond its rated operating conditions. Note 2: Slew rate is measured with 50Ω source impedance at 25oC. Slew rate is measured between VO = +5V and -5V. Note 3: The test circuit consists of the human body model of 120pF in series with 1500Ω. Note 4: The maximum power dissipation is a function of T J(max), θJA and TA. The maximum allowable power dissipation at any ambient temperature is PD = (T J(max) - TA)/θJA. Note 5: Limits are guaranteed by testing, correlation or periodic characterization. Information furnished by Calogic is believed to be accurate and reliable.
