AT2101
12-Bit 6MSPS A/D CONVERTER
Features
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.
˙Resolution: 12-Bit ± 0.5 LSB(DNL)
˙Maximum Conversion Rate: 6 MSPS
˙Built-in Sample and Hold Function
˙Built-in Reference Voltage
˙Single +5.0 V Power Supply
˙Three-State TTL Compatible Output
˙No Missing Code
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.
Applications
˙Video Digitizing
˙Personal Computer Video
˙Multimedia
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.
