The AN220E04 and all 5volt (Vortex Family) FPAA's are now at the end of life.

For new designs please use the AN231E04 FPAA (dpASP).

The AN220E04 is the first member of Anadigm®’s second generation FPAA family – the Anadigmvortex family. Based on a fully differential switched-capacitor architecture, this new product family features higher bandwidth, improved total harmonic distortion (THD) and the ability to implement a host of advanced functions.

Using dynamic reconfiguration, you can manipulate the loop response of your design: change filter characteristics (even the order) in response to changing environmental conditions, page functions in and out in sync with MUX settings, or simply adjust coefficients. All this without interrupting the operation of the dpASP, and all under control of automatically-generated software which is deployed using the same simple "drag-and-drop" approach as the circuit design itself.
