Offering 2 channels in 10 x 10 mm package, 16-bit ADS54J60 offers traits — >70 dBFS SNR at 1 GSPS, -159 dBFS/Hz noise floor, 86 dBc SFDR — that promote spectral purity and enable finding of weak signals in presence of large, unwanted blockers. As 14-bit, 500 MSPS ADC, ADS54J54 offers 4 channels in 9 x 9 mm package. Both ADCs work together with 4.5 GHz LMH6401 fully differential digital variable gain amplifier (DVGA) to provide optimal performance while reducing power and space requirements.
