buffered analog input enables operation with a

constant analog input impedance, and prevents

transient voltage spikes from feeding backward to

the analog input source. Full temperature DNL performance allows for industrial application with the assurance of no missing codes. The typical integral nonlinearity (INL) for the THS1050 is less than one LSB. The superior INL curve of the THS1050 results in SFDR performance that is exceptional for a 10-bit analog-to-digital converter. The THS1050 can operate with either internal or external references. Internal reference usage selection is accomplished simply by externally connecting reference output terminals to reference input terminals.
