The THS1050 is a high-speed low-noise 10-bit ^{VREFOUT– 6}
CMOS pipelined analog-to-digital converter. A ^{VREFIN– 7}
differential sample and hold minimizes even order ^{VREFIN+ 8}
harmonics and allows for a high degree of ^VREFOUT^{+ 9}
common-mode rejection at the analog input. A

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.
