General Description
The HT82V24 is a complete analog signal processor for
CCD imaging applications. It features a 3-channel archi-
tecture designed to sample and condition the outputs of
tri-linear color CCD arrays. Each channel consists of an
input clamp, Correlated Double Sampler (CDS), offset
DAC and Programmable Gain Amplifier (PGA), and a
high performance 16-bit A/D converter.
The CDS amplifiers may be disabled for use with sen-
sors such as Contact Image Sensors (CIS) and CMOS
active pixel sensors, which do not require CDS.
The 16-bit digital output is multiplexed into an 8/4-bit
output word that is accessed using two/four read cycles.
The internal registers are programmed through a 3-wire
serial interface, which provides gain, offset and operat-
ing mode adjustments. HT82V24 supports ADI/WM
mode data output formats.
The HT82V24 operates from a single 5V power supply,
typically consumes 380mW of power.
Applications
Flatbed document scanners
Film scanners
Digital color copiers
Multifunction peripherals
