description
The THS1050 is a high speed low noise 10-bit
CMOS pipelined analog-to-digital converter. A
differential sample and hold minimizes even order
harmonics and allows for a high degree of
common mode rejection at the analog input. A
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.
