The fast slew rate, wide bandwidth, and high output drive make the CLM4121 family the ideal choice for closed loop buffer applications with wide band op amps. These same characteristics are the excellent choices for open loop applications such as driving coaxial and switched pair cables.

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. For accurate measurements, the input slew rate should be at least 5000V/µs. 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. Note 6: For M & N package, θJA is measured by soldering the unit directly on a printed circuit board and V - pins are connected to 2 square inches of 2 oz copper.
