Featuring more than half the power dissipation of other available 14-bit analog-to-digital converters (ADCs), Texas Instruments' ADS5500 125-Msample/s ADC maintains high performance with resolution higher than any comparable device. Also, its power dissipation is only 750 mW at a 3.3-V single-supply operation. The ADC's pipeline architecture enables it to deliver a 750-MHz bandwidth with 70 dB of signal-to-noise ratio (SNR) and 82 dB of spurious-free dynamic range (SFDR) at a 100-MHz input frequency as well.
The unit includes an internal reference, accepts a differential 2-V p-p full-scale range analog input, and has a Data Ready output clock. This suits it for communications applications like wireless infrastructures, software-defined radios, and broadband wireless systems. The ADS5500 also will find use in automatic-test-equipment systems, waveform analysis, telecom testing, medical magnetic-resonance imaging (MRI), high-definition cameras, high-end scanners, and video inspection.
Available now in a 64-TQFP PowerPad package, samples go for $95 each in 1000-piece quantities (suggested resale pricing). Evaluation modules also are available. Production quantities are slated for the first quarter.
