ADC claims sampling speed record
Three new gigahertz-speed analogue-to-digital convertors are claimed to offer the industry's best performance with ultralow power consumption.
National Semiconductor has expanded its popular family of gigahertz-speed analogue-to-digital convertors (ADCs) with the introduction of three new devices that offer the industry's best performance with ultralow power consumption The new products are: the ADC08D1500, a dual 8bit convertor capable of sampling one analogue input at 3Gsample/s when operating in dual-edge sampling (DES) mode or two inputs at 1.5Gsample/s; the ADC08D500, a dual, 500Msample/s 8bit convertor; and the ADC081500, a single version of the ADC08D1500

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 ADCs join the ADC08D1000 and ADC081000, ultra-low-power gigahertz-speed ADCs introduced last year.
"Gigahertz sampling speeds and excellent dynamic performance used to be synonymous with high power consumption".
"Today, National is raising the bar with the first 8bit ADC capable of sampling signals at 3Gsample/s while consuming a mere 1.9W".

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.
"This ADC delivers on both performance and low power consumption", said Antonio Visconti, Product Line Director of National Semiconductor's Data Conversion Division.
"National's ultra-high-speed data convertors stimulate innovation".
"Every time we increase performance and sampling speed, we enable new architectures in communications systems and test and measurement equipment where these ADCs are employed".
The new dual ADCs' low power consumption of less than 2W enables engineers to design without fans and heatsinks, saving board space, reducing system cost and enhancing system reliability.
The ADC08D1500 typically achieves 7.2 effective number of bits (ENOB), 45.5dB signal-to-noise ratio (SNR) and 53.4dB spurious free dynamic range (SFDR) at 3Gsample/s with a 750MHz input signal.
The products guarantee no missing codes over the full operating temperature range of -40 to +85C.
The ultra-high-speed 8bit family is well-suited for test and measurement equipment such as digital oscilloscopes, digital capture cards, spectrum analysers and communications transceiver applications.
The ADC08D500 and ADC08D1500 join National's ADC08D1000, a dual gigahertz-speed ADC that outperforms competing solutions while consuming significantly less power.
Like the ADC08D1000, the ADC08D1500 and ADC08D500 digitise two input signals to 8bit resolution at sampling rates of 1.5Gsample/s and 500Msample/s, respectively, while consuming just 1.9 and 1.4W from a 1.9V nominal supply.
In DES mode, the ADC08D1500 achieves sampling speeds up to 3Gsample/s from one channel by interleaving the two on-chip convertors.
A three-wire serial bus controls on-chip functionality such as DDR (double datarate), SDR (single datarate) and DES (dual edge sampling), and independent gain and offset fine-tuning for I and Q channels.
The ADC081500 is a single version of the dual ADC08D1500.
The ADC08D500, ADC081500 and ADC08D1500 are priced at $125, $215 and $350, respectively.
All pricing is for 1000-unit quantities.
