AFE General Purpose 1ADC 12-Bit 3.3V 64-Pin LQFP T/R

The VSP5010 is a complete application-specific standard product (ASP) for charge-coupled device (CCD) line sensor applications such as copiers, scanners, and facsimiles. The VSP5010 provides two independent line-processing channels, and performs analog front-end (AFE) data processing and analog-to-digital conversion. Each channel features correlated double sampling (CDS) and sample-and-hold (S/H) processing stages, 14 analog-to-digital converter (ADC) blocks, a digital programmable gain amplifier (DPGA), and an optical black (OB) correction loop. Data are output in a 12-bit word; two-channel ADC data are multiplexed and then output.The VSP5010 operates from a single 3.3-V supply. The device is available in an LQFP-64 package.
