Anadigm fields reconfigurable analog device

Answering critics who maintain that programmable analog represents a limited market, Anadigm Inc. has come out swinging. The company has not only cracked the formula for small production runs, president Michael Kay said, but will push open new markets with a dynamically reconfigurable device it has just introduced.

Anadigm reports user success stories for its field-programmable analog arrays (FPAAs). The devices, replacing multiple analog ICs and passives with a single package, are primarily for signal-conditioning applications, Kay said, and the typical Anadigm customer uses 1,000 to 100,000 per project.

These small production runs for analog circuits are a lot larger than the prototypes for which the analog blocks were slated - and a potentially profitable business with high average selling prices.

But the company's latest devices are reconfigurable processors that allow real-time parameter changes. Analog functions are developed in software and "compiled" with an embedded system.

An embedded core - C-programmable and SRAM-based - in the Anadigmvortex device (the AN220E04) allows analog signal conditioning to be "adaptive." Reconfigurability paves the way for fully-adaptive circuits, Kay insisted. The 220 Anadigmvortex replaces 20 separate analog blocks, Kay said, and already has nine design wins.

The company can already report design wins and shipments for its statically reprogrammable devices. They are used for low-frequency signal-conditioning applications (under 2MHz), references, signal generators, amplifiers, and filters as well as for control of phase and frequency, added Kay. Markets include industrial controls and monitoring, photonics (laser tracking), and automotive controls.

The dynamically reprogrammable 220 Anadigmvortex has four differential inputs and two output cells (for conditioning/monitoring applications in low-voltage differential signaling), a 170MHz op amp (with a 150V/5s slew rate), an 8-bit SAR ADC, and a switched capacitor fabric.

The device offers a SNR of up to 100dB for audio signals and a CMRR of >80dB for signal-conditioning circuits. It is priced at $15 each in lots of 10,000.
