Texas Instruments VSP7500ZWV

Description
The VSP7500/VSP7502 are four-channel analog front-ends (AFEs) for imaging signals. These devices include a correlated double sampler (CDS), programmable gain amplifier (PGA), analog-to-digital converter (ADC), input clamp, optical black (OB) level clamp loop, serial interface, and adjustable sampling timing control. The VSP7502 provides the same functionality with a sample/hold (S/H) mode to support CMOS and CIS sensors.
