HT82V26A -- 16-Bit CCD/CIS Analog Signal Processor
General Description
The HT82V26A is a complete analog signal processor for CCD imaging applicati***. It features a 3-channel architecture designed to sample and condition the outputs of tri-linear color CCD arrays. Each channel c***ists 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 c***umes 400mW of power.
