description

The TLC8044 is a 12-bit analog-to-digital interface subsystem for charge-coupled device (CCD) image sensors

and scanners. An input multiplexer allows color operation with a single on-chip 12-bit ADC. The TLC8044 uses

DSP circuits to correct for nonideal CCD image sensor and scanning system characteristics. Cost effective gray

scale operation is obtained using a single multiplexer input. The TLC8044 three-channel input multiplexer and

sampling function has two basic modes of operation: normal sampling and correlated double sampling. The

internal sample and hold allows all three channels to be sampled simultaneously in color operation. Three DACs

(8 bits + sign) are provided to allow bipolar adjustment of the dc level of the signal at the ADC input. Digital dc

restoration is provided following the ADC. Variations in offset and luminance across a scan are dynamically

corrected on a pixel-by-pixel basis, using calibration data provided by an external data store. Provisions are

made for global adjustments of gain, contrast and color balance, and offset for brightness. The output word

length can be programmed to 8, 10, 12, or 16 bits, and a programmable threshold detector is provided for use

during calibration and OCR applications. The TLC8044 is characterized for operation from 0°C to 70°C.
