AT2101 Datasheet | Aimtron Technology

Features ˙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 patible Output ˙No Missing Code General Description 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. The AT2101 operates from a single +5.0V power supply. All digital inputs are CMOS patible and the tri-state outputs are TTL-patible. The AT2101 is ideal for most video and image processing applications that require low power dissipation and low cost.
