VSP2590 说明

The VSP2590 is a dual-channel analog front-end for processing imager output signals. The device includesa correlated double sampler (CDS), programmable gain amplifier (PGA), analog-to-digital converter (ADC), input clamp, optical black (OB) level clamp loop, serial interface, adjustable sampling timing control, and reference voltage generator. The VSP2590 also provides a sample/hold (S/H) input mode.

The VSP2590 is offered in a BGA-159 package and operates on a single +3 V supply.
