Speedy ADC doesn't compromise on
performance
Atmel has released what it reckons is the industry's fastest, commercially available, monolithic 12bit analogue-to-digital convertor with a clock frequency of 500Msample/s.
Atmel has released what it reckons is the industry's fastest, commercially available, monolithic 12bit analogue-to-digital convertor (ADC) with a clock frequency of 500Msample/s The AT84AS001TP will allow system designers to accurately digitise signals with frequencies up to 250MHz at sampling rates that could not have been achieved before with 12bit resolution

Controller maintains automotive system safety
With its built-in driver functions and complete monitoring system, the ATA6814 is a unique solution beneficial for all safety-relevant automotive electronics.
With current commercial offerings for 12bit ADCs limited to 250Msample/s designers are forced to use several down-conversion hardware stages before entering the analogue signals into the ADC, and to interleave several ADCs to get high datarates.
Providing a major step forward in sampling rate without compromise on performance, the AT84AS001TP will set a new standard, allowing simpler system architectures while offering the possibility to sample wider bandwidth signals.
This will benefit many applications including telecommunications infrastructure, high IF broadband digital receivers, test and measurement equipment, high-speed data acquisition and defence radar and communications systems.

Two new 8bit AVR Flash microcontrollers feature extended Controller Area Network capabilities.
Thanks to its 0.5dB band flatness from DC to 250MHz, the AT84AS001TP provides an impressive 62dBc SNR, 75dBc SFDR and 10 ENOB at 500Msample/s over the first Nyquist zone with two-tone intermodulation distortion (IMD) limited to -70dB.
This high level of performance is achieved while dissipating a very moderate 2.3W with 3.3V and 5V power supplies.
The required analogue input signal amplitude is only 1.1V peak-peak, and can be AC or DC coupled.
An integrated three-wire serial interface offers convenient software control of the ADC gain and offset.
"The AT84AS001TP is clearly a step ahead of the competition, being the first monolithic 12bit ADC available on the market to provide a guaranteed 500MHz sampling rate without any compromise on performance", said Jean-Charles Terrien, Strategic Marketing Manager for Atmel's Broadband Data Conversion product line.
"This ADC is the first of a new high-resolution family and reaffirms Atmel's commitment to pushing the state-of-the-art in terms of the speed/resolution compromise, enabling designers to lower system complexity and cost".
The AT84AS001TP is available in a TBGA192 plastic package and will be offered in both commercial and industrial temperature ranges.
Samples are available now, with production quantities in Q4 2006, at a unit price of $98 for a 1000-piece quantity in commercial grade.
