WM8150 General Description
The WM8150 is a 12-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 8MSPS.
The device includes a complete analogue signal processing channel containing Reset Level Clamping, Correlated Double Sampling, Programmable Gain and Offset adjust functions. Internal multiplexers allow fast switching of offset and gain for line-by-line colour processing. The output from this channel is time multiplexed into a high-speed 12-bit Analogue to Digital Converter. The digital output data is available in 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, a digital core voltage of 5V, and a digital interface supply of either 5V or 3.3V, the WM8150 typically only consumes 160mW when perating from a single 5V supply.
