The WM8199SCDS/RV is a 16-bit analogue front end and digitiser IC designed to process and digitise analogue output signals from CCD sensors or Contact Image Sensors (CIS). It supports pixel sample rates of up to 20MSPS at 16-bit resolution, with an extended rate of 30MSPS at 8-bit resolution. The device operates on a single 5V supply or dual 5V/3.3V supplies, consuming typically 358mW. Key internal features include correlated double sampling, programmable gain with 8-bit resolution, programmable offset adjust, and programmable clamp voltage. Data output formats are configurable as 8-bit or 4-bit wide multiplexed interfaces.
The WM8199 series belongs to Cirrus Logic's family of CIS/CCD analog front ends. The 'SC' suffix typically denotes specific temperature or performance grades within the Wolfson/Cirrus portfolio. The 'DS/RV' package designation indicates a 28-lead SSOP form factor with reel packaging variants. This component serves as a dedicated interface between optical sensors and digital processing units in imaging systems.
Direct pin-compatible replacements within the same family include the WM8199CDR and WM8199CDS. Designers should verify that the alternative package type matches the PCB footprint and that the thermal characteristics align with the application requirements.
