AFE ICs accelerate industrial image scanning
Cirrus Logic has launched the CS82L4x series of analog front-end (AFE) chips for CIS and CCD sensors in scanners and industrial imaging platforms. Based on a redesigned SAR ADC architecture, the devices are said to offer faster scan times and enhanced efficiency, while an integrated RGB LED driver reduces design complexity.
The CS82L41, CS82L44, and CS82L46 provide one, four, and six channels, respectively, with a conversion rate of 24 Msamples/s per channel. With 16-bit resolution, the AFE ICs convert LED reflections from scanned objects into accurate digital representations. Per-channel signal conditioning includes reset level clamping, correlated double sampling, and programmable polarity, gain, and offset adjustment.
Operating from a 3.3-V supply, the CS82L4x series provides a scalable platform for multi-lens and multichannel scanning architectures across a range of imaging systems. The CS82L41 features an SPI control interface with CMOS output. The CS82L44 and CS82L46 offer SPI or I²C control interfaces, CMOS or LVDS outputs, and integrated sensor timing generation. All devices operate over a temperature range of −40°C to +85°C and come in QFN packages.
Samples are available now from Cirrus.
