National Semiconductor?s 30msps 10-bit ADC Offers Highest Effective Number of Bits, Lowest Offset Voltage to Ensure Best Signal Quality

ADC10030 Features Lowest Active and Standby Power for Communications, Games, Imaging and Video Applications

August 30, 1999 ? National Semiconductor? Corporation today announced the 30MSPS, 10-bit ADC10030, which is designed to ensure the best signal fidelity during analog to digital conversion and the most efficient power consumption for a variety of demanding applications. With these and other features, the ADC10030 is well suited for communications, games, and imaging and video applications.

"To ensure the highest quality digitized signal, the 10-bit ADC10030 offers customers the best signal-to-noise ratio at 59dB, the highest effective number of bits at 9.4 and the lowest input offset voltage error at 6mV in the marketplace. These leading specifications along with the combination of the lowest 1mW standby power and 150mW active power, provide designers with an unbeatable ADC for many applications,? said Chuck Traylor, marketing manager for National?s Data Conversion Systems group.

"The high effective number of bits of the ADC10030 helps yield the industry-leading signal-to-noise ratio. Other ADCs have effective numbers of bits that are two bits less than advertised, yielding lower signal-to-noise ratios and lower signal fidelity,? Traylor said. ?The extremely low 6mV input offset voltage error -- a measure of the signal?s high quality -- easily separates the ADC10030 from the nearest competitor, which has a spec six times higher.?

Another measure of how well an ADC converts signals is the DNL (differential non-linearity) specification. On the ADC10030, DNL is +/-0.6 LSB (least significant bit) maximum, whereas for competing ADCs this measure of internal noise is +/-1 LSB or more.

To consume a minimum amount of board area, the ADC10030 is housed in a space-saving 32-pin TQFP (thin quad flat pack). For broader applications, it also operates over the extended industrial temperature range of -40 to +85 degrees C.

Pricing and Availability
Available now, the ADC10030 is priced at $4.50 each in 1000 unit quantities. For more information, please visit http://www.national.com/pf/AD/ADC10030.html.
