MAX1101 Datasheet | Maxim Integrated

19-1166; Rev 0; 12/96 Single-Chip, 8-Bit CCD Digitizer with Clamp and 6-Bit PGA _______________General Description The MAX1101 is a highly integrated IC designed primarily for digitizing the output of a linear CCD array. It provides the ponents required for all necessary analog functions, including clamp circuitry for blacklevel correction or correlated double sampling (CDS), a three-input multiplexer (mux), and an 8-bit analog-todigital converter (ADC). The MAX1101 operates with a sample rate up to 1MHz and with a wide range of linear CCDs. The logic interface is serial, and a single input sets the bidirectional data line as either data in or data out, thus minimizing the I/O pins required for munication. Packaged in a 24-pin SO, the MAX1101 is available in the mercial (0°C to +70°C) temperature range. ____________________________Features o 1.0 Million Pixels/sec Conversion Rate o Built-In Clamp Circuitry for Black-Level Correction or Correlated Double Sampling o 64-Step PGA, Programmable from Gain = -2 to -10 o Auxiliary Mux Inputs for Added Versatility o patible with a Large Range of CCDs o 8-Bit ADC Included o Space-Saving, 24-Pin SO Package ________________________Applications Scanners Fax Machines Digital Copiers CCD Imaging ______________Ordering Information PART MAX1101CWG TEMP.
