General Description
The AT2101 is a pipeline CMOS analog-to-
digital converter with modified coding algorithm
and capable of digitizing full-scale analog input
signals into 12-bit digital words at sample rate of
6 MSPS.
This high performance converter includes a 12-
bit quantizer, high bandwidth sample/hold, and
an internal reference, which eliminates the need
for external reference circuitry. The AT2101
employs digital error correction techniques to
provide excellent differential linearity for
imaging applications.
The AT2101 operates from a single +5.0V power
supply. All digital inputs are CMOS compatible
and the tri-state outputs are TTL-compatible. The
AT2101 is ideal for most video and image
processing applications that require low power
dissipation and low cost.
