简  介:WM8192 (8 + 8) Bit Output 16-bit CIS/CCD AFE/Digitiser Product Preview, June 2000, Rev 1.0 DESCRIPTION The WM8192 is a 16-bit analogue front end/digitiser IC which processes and digitises the analogue output signals from CCD sensors or Contact Image Sensors (CIS) at pixel sample rates of up to 6MSPS. The device includes three analogue signal processing channels each of which contains Reset Level Clamping, Correlated Double Sampling and Programmable Gain and Offset adjust functions. Three multiplexers allow single channel processing. The output from each of these channels is time multiplexed into a single high-speed 16-bit Analogue to Digital Converter. The digital output data is available in 8 or 4-bit wide multiplexed format. An internal 4-bit DAC is supplied for internal reference level generation. This may be used during CDS to reference CIS signals or during Reset Level Clamping to clamp CCD signals. An external reference level may also be supplied. ADC references are generated internally, ensuring optimum performance from the device. Using an analogue supply voltage of 5V and a digital interface supply of either 5V or 3.3V, the WM8192 typically only consumes 240mW when operating from a single 5V supply. FEATURES 16-bit ADC 6MSPS conversion rate Low power – 240mW typical 5V single supply or 5V/3.3V dual supply operation Single or 3 channel operation Correlated double sampling Programmable gain (8-bit resolution) Programmable offset adjust (8-bit resolution)……
