16-bit ADC  
The WM8196 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 12MSPS.  
12MSPS conversion rate  
Low power – 320mW typical  
5V single supply or 5V/3.3V dual supply operation  
Single or 3 channel operation  
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.  
Correlated double sampling  
Programmable gain (8-bit resolution)  
Programmable offset adjust (8-bit resolution)  
Programmable clamp voltage  
8 or 4-bit wide multiplexed data output formats  
Internally generated voltage references  
28-lead SSOP package  
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.  
Serial control interface  
APPLICATIONS  
•
•
•
•
Flatbed and sheetfeed scanners  
USB compatible scanners  
Using an analogue supply voltage of 5V and a digital  
interface supply of either 5V or 3.3V, the WM8196 typically  
only consumes 300mW when operating from a single  
5V supply.  
Multi-function peripherals
