National Semiconductor Introduces New Family of 36 ADCs with Guaranteed Performance Across Speeds from 50 KSPS to 1 MSPS

Pin- and Function-compatible ADCs Allow Customers to Easily Migrate Across Resolutions and Speeds, Minimizing Engineering Costs and Development Time

Apr 4, 2005

April 4, 2005 - National Semiconductor Corporation (NYSE:NSM) today expanded its data conversion portfolio with the introduction of 12 low-power, 10- and 12-bit analog-to-digital converters (ADCs) that offer guaranteed performance across three speed ranges between 50 KSPS (kilo-samples per second) and 1 MSPS (mega-samples per second).  National plans to complete the family by the end of this summer and introduce 24 additional general-purpose ADCs, including two- and four-channel 8-bit ADCs, and single- and eight-channel products. 

“These versatile pin- and function-compatible ADCs allow customers to move from 8 to 12 bits and across three speed ranges without having to modify their boards,” said Andrew Jue, product marketing director for National’s Data Conversion Systems Group. “Our four-channel devices, for example, use the same footprint and have the same input impedance, which accommodates an easy migration to faster speeds and resolutions. These are time- and cost-saving benefits that will give engineers peace of mind that they’ll get the performance they want at any sampling rate or resolution they need.”

In consumer applications such as digital cameras, the continuous demand for newer models places tremendous pressure on engineers to develop platforms that can be easily upgraded every six to eight months.  With National’s ADCs, designers can upgrade their products by simply dropping in a higher-speed or higher-resolution National ADC without modifying their boards. National’s ability to guarantee performance across speeds of 50 to 200 KSPS, 200 to 500 KSPS, and 500 KSPS to 1 MSPS, is unique in the industry. 

“National’s combination of interchangeability and guaranteed performance over a range of speeds and resolutions is an industry first,” said Jue. “This is the first family of ADCs that truly addresses customers’ concerns about engineering development time and cost.” 

National’s new ADC family will include 8-, 10- and 12-bit parts in one-, two-, four- and eight-channel configurations across three speed ranges for a total of 36 parts covering the most common general-purpose applications.

About the General-Purpose ADCs
Each ADC features superior performance and low power.  For example, the 12-bit, two- and four-channel ADCs provide no missing codes to 12 bits, ±1LSB INL (integral non-linearity), ±1LSB DNL (differential non-linearity) and 71dB minimum SNR (signal-to-noise ratio).  Typical power consumption is as low as 1.9 mW at 3 V.  These ADCs also can be paired with one of National’s general-purpose amplifiers to provide a high-performance signal path solution.  For more information on National’s amplifiers and ADCs for the signal path, visit National’s web site http://signalpath.national.com
