ADI Design Tools: Helping you through your design challenges.
Amplifier and Linear Tools
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.
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.
Instrumentation amplifier datasheets typically show a graph (or several variations) of the Output Swing vs Input Common-Mode Voltage, also known as the Diamond Plot, which is a comprehensive graph of all external and internal headroom limits. Given enough basic information about a circuit, the Diamond Plot can be adjusted for various Supply Voltages, Gains, and Reference Pin Voltages.
Clock and Timing Tools
TimerBlox® parts are small, accurate and simple timing devices, designed for 5 basic operations: Voltage-Controlled Oscillation (VCO), Low Frequency Clocking, Pulse-Width Modulation (PWM), One-Shot Generation and Signal Delay.
To speed and simplify your design process, TimerBlox Designer is an Excel based selection and synthesis tool that allows you to choose and configure the TimerBlox part best suited for your application.
ADIsimCLK™ is the design tool developed specifically for Analog Devices' range of ultra-low jitter clock distribution and clock generation products. Whether your application is in wireless infrastructure, instrumentation, networking, broadband, ATE or other areas demanding predictable clock performance, ADIsimCLK will enable you to rapidly develop, evaluate and optimize your design. It is a highly successful tool for predicting phase noise and jitter for ADI clock products.
Data Converter Tools
For designers who are selecting or evaluating high speed ADCs, VisualAnalog? is a software package that combines a powerful set of simulation and data analysis tools with a user-friendly graphical interface. VisualAnalog allows designers to customize their input signal and data analysis.
Virtual Eval is a web application to assist designers in product evaluation of ADCs and DACs. Using detailed models on Analog’s servers, Virtual Eval simulates crucial part performance characteristics within seconds. Configure operating conditions such as input tones and external jitter, as well as device features like gain or digital down-conversion. Performance characteristics include noise, distortion, and resolution, FFTs, timing diagrams, frequency response plots, and more.
Power Management Tools
RF and Synthesis Tools
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.
ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive database of device models for ADI’s RF and mixed signal components.
