Manufactured on ADI’s proprietary XFHV high-speed bipolar process, the AD8024 is capable of driving to within 1.3 V of its 24 V supply rail. Each amplifier has high-output current capability and can drive high capacitive loads. The AD8024 outputs settle to 0.1% within 35 ns into a 300 pF load (6 V swing). The AD8024 can run on both 5 V as well as ± 12 V rails. Slew rate on ± 12 V supplies is 2400 V/µs. DC Characteristics are outstanding with typical 2 mV offset, and 3 µA maximum input bias current. High-speed disable pin allows the AD8024 to be shut down when not in use. Low-power operation is assured with the 4 mA/Amplifier supply current draw. The high voltage drive capability, low settling time, high slew rate, low offset, and high bandwidth make the AD8024 ideally suited as an LCD column driver, a video line driver, and for use in high-performance test equipment. The AD8024 is available in a 16-lead SOIC package. VOUT 2V Figure 1. Pulse Response Driving a Large Load Capacitance, C L = 300 pF, G = +3, RFB = 2.32 kΩ, RS = 10.5 Ω, RL = 1 kΩ, VS = ± 7.5 V R EV.
