Analog
an analog world of sight and sound. Therefore, analog remains strong and and continues to grow stronger. For most digital devices, analog front and back ends are required for the human human interface. The demand for analog is alive and well and will continue to trend upwards in 2011 and in the foreseeable future. Q
How many analog IC suppliers and items do you deal with? What are some of your representative analog IC vendors?
Zack Digi-Key currently offers more than 300,000 analog products from over 90 IC suppliers. And with the more than 40,000 analog products that we keep in stock, we are currently capable of shipping 93 percent of our analog inventory inventory.. Q
Digi-Key Corp. of the US provides digital products, but also oers many analog ones, which continue to see strong demand. The company has set up Supplier Index “nano-sites” for the analog products in order to build an easy-to-order Web presence and a speedy delivery system. We sat down with Mark Zack, Digi-Key’ s vice president of semiconductor products, to discuss market
Do you you have any tie-up campaigns with specic analog IC vendors to promote the products?

Zack While we see tremendous growth in analog-todigital and digital-to-analog converters, the most popular analog ICs are the entry-level devices — transistors and op amps — that proliferat e everywh ere. These basic building blocks are used in nearly every electronic device. Other popular, entry-level devices are power-management ICs. Signicant expansion in mobile-device applications is driving an increased need for power conservation, which in turn is fueling the need for small footprint, highly ecient power-management ICs. Q How do you build procurement, inventory, and delivery systems for users?
Zack Our long-standing goal is to have products in stock and available for immediate shipment 95 percent of the time. We have established inventory pipelines with all of our manufacturers to support user engineering and production needs. Q Do you purchase analog products directly from origina l equipment manufacturers?
Zack We are consistent in ensuring that our suppliers offer valid, franchised products. As a member of the Electronic Components Industry Association (the group formed by combining the Electronic Components Association and National Electronic Distributors Association), Digi-Key maintains a supplier base that we know will provide quality, non-counterfeit products to customers. Our position is that customers and manufacturers should verify their sources of electronic parts. Digi-Key is an authorized, franchised distributor for more than 470 branded suppliers. Our suppliers validate that fact on each of their websites.
