Frugal dual-channel A/D conversion
National Semiconductor has introduced a dual-channel 8bit A/D convertor with record low-power dissipation levels.
"National is well positioned to continue its growth in the high-speed market by meeting and exceeding customer expectations with innovative solutions".
National Semiconductor's ADC08L060 consumes only 0.65mW/Msample/s, while delivering the highest dynamic performance out to Nyquist, enabling its applicability in battery-powered, portable applications.
The ADC08L060 features power consumption that scales with sample rate, providing the flexibility to use the part at any conversion rate between 10 and 60Msample/s while consuming power proportional to the speed of operation.
The ADC08L060 has no clock duty cycle dependence from 5 to 91%, allowing it to be used in applications such as ultrasound imaging where beam-forming techniques may force the duty cycle of the ADC's conversion clock to deviate substantially from 50%.
The ADC12D040 provides best-in-class dynamic specifications with 68dB signal-to-noise ratio and 80dB spurious-free dynamic range.
The ADC12D040's high SNR provides superior image quality in imaging applications.
With an internal reference and selectable parallel two's-complement or binary outputs, the ADC12D040 provides a seamless interface to ASICs in ultrasound imaging systems.
The dual feature of the ADC12D040 reduces board space and system power dissipation, particularly in ultrasound applications using 128 channels.
Additionally, this device features close channel matching and virtually no cross talk.
National also offers an evaluation board and software that facilitates quick bench trials and simplifies final circuit design.
Using National's WaveVision software running under Microsoft Windows, designers can capture and display multiple waveform data from the ADC in graphical form from a menu-driven environment.
The software can also perform fast Fourier transform calculations on the data to measure the dynamic performance of the ADC, displaying signal to noise ratio, signal to noise and distortion, total harmonic distortion and spurious-free dynamic range in addition to the spectral plot from the FFT.
The ADC08L060 is available in a 24-pin TSSOP package and is priced at $3.00.
The ADC12D040, sampling now, is available in a 64-pin TQFP package and is priced at $17.00.
All prices are in 1000-unit quantities.
