Anadigm Inc. is dropping the entry price for programmable analog chips to below $5 with its field programmable analog array (FPAA) that combines dynamic reconfiguration capabilities with a resource structure optimized for cost-sensitive applications.

Priced at $4.95 in 1,000-piece quantities, the AN221E02 makes programmable analog an affordable option for simple analog filtering, sensor conditioning and basic PID control applications. Using half the Configurable Analog Block (CAB) resources of previous Anadigmvortex FPAAs, the device serves in a wide range of industrial, audio, automotive, medical, communications, automatic test equipment, and instrumentation systems.

Statically and dynamically reconfigurable, the AN221E02 allows on-the-fly, real-time control of analog functions by the microprocessor in an embedded system. Using dynamic reconfiguration, designers can manipulate the loop response of their design, change filter characteristics in response to shifting environmental conditions, or adjust coefficients without interrupting the operation of the FPAA.

The product features two configurable I/O cells that can serve as inputs or outputs, plus two dedicated output cells. Its fully differential architecture provides a signal-to-noise range of 80dB for broadband and 100dB for narrowband (audio) applications. Typical bandwidth ranges from dc to 2MHz depending on function.

A complete evaluation kit with a development board, entry-level software, and updated documentation is available for $199.
