GENERAL DESCRIPTION

The Ai4100 is a CMOS single-chip signal processing

devices for CCD area sensors. It consists of a clamp

circuit, Correlated D o u b l e S a m p l e r ( C D S ) ,

Programmable Gain Amplifier (PGA), reference

voltage generator, black level detection circuit,

20MHz 10-bit A/D converter (ADC), timing generator

for internally required pulses and serial interface for

internal function control and PGA gain control.
