HT82V24 -- 16-Bit, 15MSPS, 3-Channel CCD/CIS Analog Signal Processor

General Description

The HT82V24 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 8/4-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 operating mode adjustments. HT82V24 supports ADI/WM mode data output formats.

The HT82V24 operates from a single 5V power supply, typically consumes 380mW of power.
