The AN120E04 and all 5volt (Vortex Family) FPAA's are now at the end of life.

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

The AN120E04 is a member of Anadigm®’s second generation FPAA family – the Anadigmvortex family. Based on 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 relative to Anadigm®’s first generation product. The AN120E04 device provides a low-cost path to implementing analog signal conditioning in high-volume applications.
