Texas Instruments VSP5000PMR

Description
The VSP5000 is an application-specific standard product (ASSP) designed for charge-coupled device (CCD) line sensor applications in copiers, scanners, and facsimiles. It provides two independent channels of processing lines, performing analog front-end processing and analog-to-digital (A/D) conversion. Each channel includes a correlated double sampler (CDS)/sample hold (SH) circuit, a 14-bit analog-to-digital converter (ADC), a digital programmable gain amplifier (DPGA), and an optical black (OB) correction loop. Data output is 12 bits in length, with the 2-channel A/D data multiplexed and output.
