FET Input Amplifiers

Analog Devices' High Speed (>50MHz) FET input op amps or FastFET™ provide high input impedance and ultra low input bias currents for high speed applications. The majority of our FET input op amps feature wide supply ranges from 5 to ±12V or higher and feature rail-to-rail outputs enabling wide dynamic range.

  • Filter Filter
    Analog Filter Wizard 2.0

    The Analog Filter Wizard™ helps you design a low-pass, high-pass, band-pass or band-stop filter with actual op amps. It then simulates the filter’s performance with these op amps in real time. You can ask the tool to optimize for power, noise, or voltage range, and it will pick op amps and passive components appropriately. Or you can adjust the components manually yourself.

  • Photodiode Photodiode
    Analog Photodiode Wizard

    The photodiode web tool helps you select and design the best circuit for your application. To use the tool, enter the specifications of your light input, including intensity, spectral band, and the required signal bandwidth. These inputs will narrow down the available photodiode part numbers.

  • ADIsimADC ADIsimADC
    ADIsimADC

    The ADIsimADC tool is an aid to help in the selection of Analog to Digital Converterse (ADC's), perform evaluations and assist with troubleshooting. The tool uses typical data values to mathematically model the general behavior of the selected ADC. It allows a user to apply input signals, set encode (sample) rates and simulate FFT's on a selected ADC. It is useful for checking the SNR, SFDR, SINAD, THD, ENOB etc. of a selected ADC.

  • ADIsimDAC ADIsimDAC
    ADIsimDAC

    ADIsimDAC assists the user with finding Analog Devices' DACs and DAC Application Circuits. It takes user inputs along Typical Parametric Data to sort, select and suggest applicable DAC's, system components and circuit solutions.

  • ADIsimRF ADIsimRF
    ADIsimRF

    ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded Gain, Noise Figure, IP3 and P1dB as well as total power consumption are calculated. The number of stages can be varied up to a maximum of 15. Additional stages can be inserted at any point in teh signal chain and individual stages can be temporarily disabled or deleted. The calculator can be switched between Transmit Mode and Receive Mode where calculations are presented output-referred and input-referred respectively.

  • ADIsimPLL ADIsimPLL
    ADIsimPLL

    The ADIsimPLL design tool is a comprehensive and easy-to-use PLL synthesizer design and simulation tool. All key non-linear effects that can impact PLL performance can be simulated, including phase noise, Fractional-N spurs, and anti-backlash pulse. ADIsimPLL design tool eliminates time-consuming iterations from the PLL/synthesizer development process.

  • ADIsimPower ADIsimPower
    ADIsimPower

    ADIsimPower™ Voltage Regulator Design Tool produces custom DC-DC converter designs in about one minute. The user enters 5 inputs and chooses to optimize for efficiency, PCB space, cost, or part count. Output is a complete schematic, BOM, efficiency plot, and performance summary. A PDF summary and a blank PCB is offered for each design to facilitate fast prototyping to verify the design.

  • Digital Power Management Digital Power Management
    Digital Power Management

    ADI's digital PWM (pulse-width modulation) power control and management devices provide designers with a highly integrated circuit architecture and the flexibility to configure system power-supply parameters in a matter of minutes using an intuitive GUI (graphical user interface). Power design egnineers with no prior programming experience can use the GUI to monitor and quickly adjust power functions such as frequency, timing, voltage settings, and protection limits.
