14bit A/D conversion at 105Msample/s
Analog Devices is claiming another industry breakthrough with the first 14bit ADC to run at 105Msample/s.
Developed using a combination of innovative design processes and packaging techniques, the convertors are ideal for voltage level setting applications used in a wide range of communications, consumer and handheld battery-powered designs including digital cameras, projectors and PDAs.
"With manufacturers designing their products in ever decreasing form factors, especially in the communications field, there has been a continual push for cost-effective components that deliver increased performance in smaller packages", said Mike Britchfield, Product Line Director for Precision Convertors, Analog Devices.
"The devices in the nanoDAC family address these design challenges by consuming considerably less power and space than comparable solutions".

DSP needs no ASICs to run software basestations
Analog Devices has unveiled a new DSP equipped with Layer 1 software that together are claimed to reduce system costs of 3G infrastructure equipment by up to 50%.
Leading the nanoDAC family's product offerings is a device claimed as the world's smallest, low-power D/A convertor.
Available in a compact SC-70 package, the AD5641 consumes 70% less board area and 80% less power than comparable devices.
Delivering 14bit resolution and guaranteed monotonic behaviour with a maximum power consumption of 100uA at 5V, the AD5641 combines fine output control with low power in a compact footprint.
The combination of small package and low power consumption make the AD5641 ideal for voltage level setting requirements such as generating bias or control voltages in space-constrained low power wireless applications, including cell phone volume controls and screen lighting.
In addition to the AD5641, Analog Devices is introducing the AD5621 (12bit), AD5611 (10bit) and AD5601 (8bit).
These lower resolution devices provide suitable alternatives for applications not requiring the performance of the AD5641.
Leading-edge packaging technology The AD5641 is designed using a combination of Analog Devices' patented "segmented string" architecture, which offers unmatched accuracy in the smallest die area, and patented advanced chip-on-lead (COL) die packaging technology.
The string architecture is segmented in substrings to provide significant die size savings, and the COL assembly technology maximises package cavity size and therefore minimises the customer's board footprint.
Both innovations enable these products to provide customers with the best value on the market today, in terms of price and performance.
The AD5641 (14bit), AD5621 (12bit), AD5611 (10bit) and AD5601 (8bit) are sampling now and will be available in production quantities in December 2004.
Each part is available in 6-lead SC-70 packaging with 1000-off prices ranging from $0.95 to $4.75, depending on the resolution and accuracy combination.
