Cirrus Logic has introduced a new family of industrial imaging ICs for high-precision scanning applications:the CS82L41, CS82L44 and CS82L46.
Designed as analog front-end devices for CCD and CIS sensors, this product family supports scalable imaging architectures with single-, four- and six-channel options. With pixel conversion rates up to 24 MSPS per channel, these devices help engineers convert analog sensor signals into accurate digital data for demanding scan and imaging systems.
This makes the family relevant for applications such as:
• Multifunction printers and scanners
• Industrial imaging platforms
• Machine vision and inspection systems
• High-precision scan heads
• Compact embedded imaging designs
The value for is clear: accurate signal processing, scalable channel options and reduced system complexity in applications where imaging quality, timing and reliability matter.
CS82L41
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.
