10-bit CCD signal processor — 48-LQFP
The AD9804JST is a complete 10-bit 18 MSPS CCD signal processor from Analog Devices, part of the AD9804 series. It integrates the analog front-end and ADC for charge-coupled device (CCD) image sensor readout, handling correlated double sampling, programmable gain, and A/D conversion in a single chip. The single-channel architecture targets line-scan or area-scan CCD applications where 10-bit resolution at 18 MSPS is sufficient.
The part is stocked and shipped as Bulk (tray or tube), consistent with the listed package option.
Peer comparison — bit depth and resolution delta
The closest functional peer within the same catalog is the AD9876BST, a 12-bit CCD signal processor in the same 48-LQFP footprint. The AD9804JST offers 10-bit resolution at 18 MSPS versus the AD9876BST's 12-bit resolution — a 2-bit difference that matters when the downstream system requires 12-bit dynamic range for low-light CCD readout.
