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
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.
Level Clamping,
Correlated
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
operating from a single 5V supply.
