AD623 Single Supply
Calculates value of Rg based on desired gain. Illustrates internal nodes of 3-opamp architecture and alerts user when internal
or external limits are exceeded.
AD623B Error Budget Analysis
Calculates absolute accuracy and resolution based on error sources within the amplifier. This tool uses data for the specific
quality grade of amplifier and your applications parameters to calculate the error budget in ppm.

AD623 Dual Supply
Calculates value of Rg based on desired gain. Illustrates internal nodes of 3-opamp architecture and alerts user when internal
or external limits are exceeded.
Analog Bridge Wizard
The Analog Bridge Wizard recommends amplifiers and ADC's for your bridge application. Find out which op-amp or in-amp is
best for your design, and view the error budget analysis for that solution.
