| 4mW, 180MHz, 2000V/s High Speed Buffer CORPORATION CLM4122 / CLM4322 FEATURES GENERAL DESCRIPTION The CLM4122 family are low power, high speed unity gain buffers that slew at 2000V/s, having a small signal bandwidth of 180MHz, delivers 60mA, yet draws only 800A supply current. The 4mW power consumption, fast slew rate, wide bandwidth, and high output drive make the CLM4122 family the ideal choice for battery operated equipment. These same characteristics are the excellent choices for 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 50 source impedance at 25oC with input DC offset to 2.5V. For accurate measurements, the input slew rate should be at least 5000V/s. Note 3: The test circuit consists of the human body model of 120pF in series with 1500. Note 4: The maximum power dissipation is a function of T J(max), JA and TA. The maximum allowable power dissipation at any ambient temperature is PD = (T J(max) - TA)/JA. Note 5: Limits are guaranteed by testing, correlation or periodic characterization. Note 6: For M & N package, JA 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.
