General Description
The HT82V842 is a CMOS single-chip signal process-
ing device for CCD area sensors. It consists of a clamp
circuit, Correlated Double Sampler (CDS), Programma-
ble Gain Amplifier (PGA), reference voltage generator,
black level detection circuit, 20MHz 10-bit A/D converter
(ADC), timing generator for internally required pulses,
serial interface for internal function control and PGA
gain control.
