High performance 1-channel imaging Analog Front-End with CMOS Data Output
The CS82L41 is a front-end device for CCD and CIS sensors. The CS82L41 processes and digitizes the analog sensor signal at pixel conversion rates of up to 24 MSPS.
The signal processing includes reset level clamping (RLC), correlated double sampling (CDS), and programmable polarity, gain and offset adjustment. Voltage references may be generated by an internal DAC or else provided externally.
The output data is available in a variety of CMOS digital formats.
The CS82L41 incorporates an RGB LED driver with programmable current sinks and timing control. White LEDs are also supported.
The 3.3 V supply may be provided directly, or else generated using an on-chip LDO. An additional LDO provides a 3.4 V supply for an external sensor.
The CS82L41 is available in a commercial-grade 0.4 mm pitch, 28-pin QFN package for operation from –40° to +85°C.
