The AD8042 is a low power voltage feedback, high speed amplifier designed to operate on +3 V, +5 V or ± 5 V supplies. 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.
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 differential 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 Analog-to-Digital converters (ADCs).
The AD8042 offers low power supply current of 12 mA maximum 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/µs 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 PDIP and SOIC_N packages.

Power Dissipation vs Die Temp
This tool estimates die temperature and power dissipation based on the supply voltages, ambient temperature, load characteristics, and package thermal data.
Open ToolAnalog Filter Wizard
Use the Analog Filter Wizard to design low-pass, high-pass, or band-pass filters with actual op amps in minutes. As you progress through the design process, you can observe the characteristics of your filter design from ideal specifications to real world circuit behavior. Quickly evaluate the tradeoffs in op amp specifications - including gain-bandwidth, noise, and supply current – to determine the best filter design for your requirements.
Open ToolAnalog Photodiode Wizard
Use Photodiode Wizard to design a transimpedance amplifier circuit to interface with a photodiode. Select a photodiode from the library included in the tool, or enter custom photodiode specifications. Quickly observe tradeoffs between Bandwidth, Peaking (Q), and ENOB/SNR. Modify circuit parameters, and immediately see results in plots for pulse response, frequency response, and noise gain.
