PRODUCT ION DE SCRIPT ION
T he AD9807 and AD9805 are complete CCD/CIS imaging
decoders and signal processors on a single monolithic integrated
circuit. T he input of the AD9807/AD9805 allows direct ac
coupling of the charge-coupled device (CCD) or contact image
sensor (CIS) output(s). T he AD9807/AD9805 includes all the
circuitry to perform three-channel correlated double sampling
(CDS) and programmable gain adjustment of the CCD output;
a 12-bit or 10-bit analog-to-digital converter (ADC) quantizes
the analog signal. After digitization, the on-board digital signal
processor (DSP) circuitry allows pixel rate offset and gain correc-
tion. T he DSP also corrects odd/even CCD register imbalance
errors. A parallel control bus provides a simple interface to
8-bit microcontrollers. T he AD9807/AD9805 comes in a
space saving 64-pin plastic quad flatpack (PQFP) and is specified
over the commercial (0
°
C to +70
°
C) temperature range. By
disabling the CDS, the AD9807/AD9805 are also suitable for
non-CCD applications, or applications that do not require
CDS, such as CIS signal processing.
PRODUCT HIGHLIGHT S
T he AD9807/AD9805 offers a complete, single chip CCD
imaging front end in a 64-pin plastic quad flatpack (PQFP).
On-Chip PGA
—T he AD9807/AD9805 includes a 3-channel
analog programmable gain amplifier; it is programmable from
1
×
to 4
×
in 16 increments.
On-Chip CDS
—An integrated 3-channel correlated double
sampler allows easy ac coupling directly from the CCD sensor
outputs. Additionally, the CDS reduces low frequency noise
and reset feedthrough.
On-Chip Voltage Reference
—T he AD9807/AD9805 includes a
2 V bandgap reference that allows the input range of the device to
be configured for input spans up to 4 V.
6 MSPS A/D Converter
—A highly linear 12-bit or 10-bit A/D
converter sequentially digitizes the red, green and blue CDS
outputs ensuring no missing code performance. T he user may also
configure the AD9807/AD9805 for single channel operation.
Digital Gain & Offset Correction
—Pixel rate digital gain and
offset correction blocks allow precise repeatable correction of
imaging system error sources.
Digital I/O Compatibility
—T he AD9807/AD9805 offers
+3.3 V/+5 V logic level compatibility.
Pin-Compatible 12-Bit and 10-Bit Versions—
T he AD9807 is
also offered in a pin-compatible 10-bit version, the AD9805,
allowing upgrade-ability and simplifying design issues across
different scanner models.
