Description

The SCDS4D28T-4R7T-B-N is a 12-bit analogue front end/digitiser IC that is designed to process and digitise the analogue output signals from CCD sensors or Contact Image Sensors (CIS) at pixel sample rates of up to 8MSPS. It is commonly used in electronic devices that require high-performance CCD sensor interfaces.

Specifications and features

The SCDS4D28T-4R7T-B-N features a 12-bit ADC with an 8MSPS conversion rate. It operates on a low power of 170mW typical and can be used with either a 5V single supply or 5V/3.3V dual supply. The IC supports single channel operation and includes correlated double sampling and programmable gain and offset adjustments. It also has a programmable clamp voltage and uses a 4-bit wide multiplexed data output format. The SCDS4D28T-4R7T-B-N comes in a 20-pin SSOP package and includes a serial control interface.

Application Scenarios

The SCDS4D28T-4R7T-B-N is commonly used in various electronic devices, including flatbed and sheetfeed scanners, USB compatible scanners, multi-function peripherals, and other devices that require a high-performance CCD sensor interface.
