DescriptionThe 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 HT82V26A 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 of HT82V26A 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.
