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. The
VSP7500/VSP7502 are offered in a BGA-159
package.
