Product Details

The AD8055 (single) voltage feedback amplifier offers bandwidth and slew rate typically found in current feedback amplifiers. Additionally, this amplifier is easy to use and available at a very low cost.

Despite its low cost, the AD8055 provides excellent overall performance. For video applications, its differential gain and phase error is 0.01% and 0.02° into a        150 W load, and 0.02% and 0.1° while driving four video loads (37.50 W).

Its 0.1 dB flatness out to 40 MHz, wide bandwidth out to 300 MHz, along with 1400 V/µs slew rate and 20 ns settling time, make them useful for a variety of high-speed applications.

The AD8055 requires only 5 mA typ/amplifier of supply current and operates on a dual ±5 V or single +12 V power supply, while capable of delivering over 60 mA of load current. The AD8055 is available in a small 8-lead PDIP, 8-lead SOIC, and 5-lead SOT-23 packages. These features make the AD8055 ideal for portable and battery powered applications where size and power are critical. This amplifier in the R-8, N-8 and RM-8 packages are available in the extended temperature range of -40°C to +125°C.

ADIsimPE Linear and Mixed-Signal Circuit Simulator – Personal Edition

ADIsimPE, which is powered by SIMetrix/SIMPLIS, is a circuit simulation suite optimized for the design and development of analog and mixed signal circuits. SIMetrix mode is ideal for the simulation of general non-switching circuits. It provides full Pspice compatibility for use with industry-standard SPICE models. SIMPLIS (SIMulation Piecewise-Linear System) mode simulates the operation of switching circuits with vastly improved robustness, speed, and accuracy compared to standard SPICE. It is particularly useful for switching power supply, PLLs, and ADC/DAC applications.

Analog 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.

Analog 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.

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.

Design Resources

ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well.  "Zero defects" for shipped products is always our goal.
