WM8170 - Wolfson Microelectronics plc

WM8170 3.3V Integrated Signal Processor for Area Array CCDs

The WM8170 is a 10-bit analogue front end/digitiser IC, which processes and digitises the analogue output signals from area array CCD sensors at pixel sample rates of up to 21MSPS. The device contains input blanking, correlated double sampling (CDS), programmable gain amplifier, black level clamp, on-board voltage reference and a 10-bit, 21MSPS ADC. Two auxi.
