It has true single supply capability with an input voltage range extending 200 mV below the negative rail and within 1 V of the positive rail. 5V 2.5V 0V 1 s 1V G = 1 RL = 2k TO +2.5V Figure 1. Output Swing: Gain = –1, VS = +5 V The output voltage swing extends to within 30 mV of each rail, providing the maximum output dynamic range. Additionally, it features gain flatness of 0.1 dB to 14 MHz while offering differ- ential gain and phase error of 0.04% and 0.06 ∞ on a single 5 V supply. This makes the AD8042 useful for professional video electronics such as cameras, video switchers, or any high speed portable equipment. The AD8042’s low distortion and fast settling make it ideal for buffering single supply, high speed A/D converters. The AD8042 offers low power supply current of 12 mA max and can run on a single 3.3 V power supply. These features are ideally suited for portable and battery-powered applications where size and power are critical. The wide bandwidth of 160 MHz along with 200 V/ ms of slew rate on a single 5 V supply make the AD8042 useful in many general- purpose, high speed applications where single supplies from 3.3 V to 12 V and dual power supplies of up to ±6 V are needed. The AD8042 is available in 8-lead plastic DIP and SOIC. 15 12 9 6 3 0 –3 –6 –9 –12 –15 110 100 500 FREQUENCY (MHz) V S = 5V G = +1 C L = 5pF R L = 2k TO 2.5V Figure 2. Frequency Response |
