Thread Summary

                The user inquired about a SPICE model for the AD654 and an equivalent IC. The support engineer confirmed that no SPICE model is available for the AD654 and suggested sharing the application details to explore precision sigma delta converters as alternatives. The user acknowledged the response and asked for an equivalent IC with a SPICE model, but no specific alternative was provided.

Hope long shut down is over. Could you provide Spice model for AD654 and equivalent IC for AD654
