Article Signal chain simulation for AD4080 20-bit 40 MSPS ADC, with ADA4945-1 High Speed ADC Driver

The attached guide offers a walkthrough on running simulations with the AD4080, a 20-bit, 40MSPS precision ADC, using the LTspice schematic (.asc file) included in the download.

AC, transient and noise simulation examples are shown.

A basic level of familiarity with LTspice is assumed. For support, you can post your questions in the LTspice forum in ADI Engineer Zone.
