GENERAL DESCRIPTION
The ADDI7006 is a highly integrated 6-channel charged-coupled
device (CCD) signal processor for high speed scanner
applications. Each channel is specified at pixel rates of up to 40
MHz, and consists of six complete analog front ends with
correlated double sampling, variable gain amplification, and 10-
bit analog-to-digital conversion. The ADDI7006 also contains a
reduced range LVDS interface for the digital data output to
reduce electromagnetic interference (EMI) concerns.
Each analog front end includes black level clamping, a VGA,
and a 40 MSPS, 10-bit analog-to-digital converter (ADC).
Operation is programmed using a 3-wire serial interface.
Packaged in a space-saving 80-lead TQFP package, the
ADDI7006 is specified over an operating temperature range of
−25°C to +85°C.
