ADCs offer speed and resolution upgrade
path
A family of 12 low-power, 10 and 12bit ADCs offers guaranteed performance across three speed ranges between 50Ksample/s and 1Msample/s.
National Semiconductor has expanded its data conversion portfolio with the introduction of 12 low-power, 10 and 12bit analogue-to-digital convertors (ADCs) that offer guaranteed performance across three speed ranges between 50Ksample/s and 1Msample/s National plans to complete the family by the end of this summer and introduce 24 additional general-purpose ADCs, including two- and four-channel 8bit ADCs, and single- and eight-channel products

World's smallest multifunction supervisory ICs
National Semiconductor has announced a family of supervisory ICs with a variety of factory-programmable features that can be configured in hundreds of possible combinations.
"These versatile pin- and function-compatible ADCs allow customers to move from 8 to 12bit 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".

Boomer shrinks stereo headphone amplification
New from National Semiconductor, the LM4811 Boomer audio amplifier is a 105mW stereo headphone amplifier for use in 3 and 5V systems requiring a headphone output and volume control.
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 200Ksample/s, 200 to 500Ksample/s, and 500Ksample/s to 1Msample/s, 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 12bit 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.
Each ADC features superior performance and low power.
For example, the 12bit, two- and four-channel ADCs provide no missing codes to 12bit, +/-1LSB INL (integral nonlinearity), +/-1LSB DNL (differential nonlinearity) and 71dB minimum SNR (signal-to-noise ratio).
Typical power consumption is as low as 1.9mW at 3V.
These ADCs also can be paired with one of National's general-purpose amplifiers to provide a high-performance signal path solution.
All 12 ADCs are available now.
Prices start at $1.30 for the ADC102S021 in 1000-unit volumes.
