12-bit, 1-Gsample/s ADC Provides Buffered Input

For simplifying analog front-end design in wide-bandwidth applications the ADS5400 emerges as the industry’s first ADC that combines 12 bits of resolution with a 1-Gsample/s sampling rate and a buffered input. The device specifies a SNR of 59 dBFS and a 75-dBc SFDR in first Nyquist, 58-dBFS SNR, and a 70-dBc SFDR. Other features include an operating temperature range from -40°C to +85°C, a thermally-enhanced, 100-pin TQFP measuring 16 mm x 16 mm, and user-selectable single- or dual-bus DDR LVDS outputs. Price is $775 each/100. TEXAS INSTRUMENTS INC., Dallas, TX. (800) 477-8924.
