Thermocouple Interface
ADI offers specialized precision thermocouple interface amplifiers that provide a simple and effective solution for measuring thermocouple temperatures. With features such as integrated cold junction compensation and a high-gain precision instrumentation amplifier, the AD849x and AD59x provide a complete signal conditioning system in one IC package customized for J and K type thermocouples. ADI’s thermocouple amplifiers provide a linear output voltage of 5mV/°C or 10mV/°C, and are suitable for use in laboratory environments as well as more hostile or uncontrolled environments, to measure a wide range of temperatures. These products will save you in cost, space, and unnecessary circuit design across a broad range of applications and industries.
Engineered. Tested. Ready to Integrate.

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
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
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.

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
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.
