AT2101 12-Bit 6MSPS A/D CONVERTER Features General Description ˙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 The AT2101 is a pipeline CMOS analog-todigital 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 12bit 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 ˙Digital Television 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.
