The HT82V26A is a complete analog signal processor
for CCD imaging applications. It features a 3-channel
architecture 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 sensors
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-bit output
word that is accessed using two read cycles. The internal
registers are programmed through a 3-wire serial
interface, which provides gain, offset and operating
mode adjustments.
The HT82V26A operates from a single 5V power supply,
typically consumes 400mW of power.
