DESCRIPTION

The VSP3000 is a complete, three-channel image
signal processor for Charge Coupled Device (CCD)
or Contact Image Sensor (CIS) systems. Each chan­nel contains sensor signal sampling, Black Level
adjustment and a programmable gain amplifier. The
three inputs are multiplexed into a high speed, 12-bit
analog-to-digital converter. Input circuitry can be
configured, by digital command, for CCD or CIS
sensors. A Black Clamp and Correlated Double
Samplers (CDS) are provided for CCD sensors. For
CIS devices, the VSP3000 provides a single-ended
sampler and a reference input. The VSP3000 is
available in a 48-lead LQFP package and operates
from 0°C to +85°C with a single +5V supply.

DISCHARGE SENSITIVITY

This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.

ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
