description
The THS1240 is a high-speed low noise 12-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 THS1240 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.
