A/D convertor measures smaller signals faster
Sigma-delta ADC achieves greater than true 16bit noise-free resolution up to 2.4kHz across all input voltages from 40mV to 5V.
SAR convertor claims record speed and accuracy
A/D convertor achieves a new level of 16bit data capture performance, with best-in-class 15bit ENOB and 10Msample/s throughput.
The 10bit AD9212 and 12bit AD9222 consume less than 100mW per channel, yielding savings of as much as 5 to 6W, compared with competing offerings in ultrasound systems containing up to 512 channels.
Industry's first 14bit, high-speed octal ADC, the AD9252, offers designers the highest dynamic range for high performance imaging applications such as radar and sensitive nondestructive testing.
The octal ADCs, available in 9 x 9mm, 64-pin LFCSPs (lead frame chip scale packages), provide a space savings of 40 to 60% over competing solutions.
For multi-channel designs, the AD9212, AD9222 and AD9252 enable higher channel counts, less complex board layout and smaller board designs.
The three new ADCs are derived from the AD9228 core, a quad design that increased dynamic range and image resolution in ultrasound equipment.
The AD9212, AD9222 and AD9252 support sampling rates up to 50Msample/s and provide serial low-voltage differential signalling (LVDS) data outputs.
Delivering the performance needed for multichannel imaging and radar systems, they enable more data conversion paths to be routed within a given printed circuit board (PCB) area.
A low noise floor is vital to medical instrumentation designers.
With 70dB signal/noise ratio (SNR) to Nyquist, the ADCs are adept at handling high sampling speeds without sacrificing performance.
Featuring internal datarate multipliers, the convertors offer improved output data flexibility with programmable clock and data alignment, as well as digital test pattern generation using a serial port interface (SPI).
The AD9212 and AD9222 are sampling now with full production quantities available in September 2006.
The 40Msample/s devices are priced at $32 and $44 in 1000 piece quantities for the AD9212 and AD9222, respectively.
At 50Msample/s, the AD9212 is $40, the AD9222 is $49 and the AD9252 is $54 in 1000 piece quantities.
