Description and Introduction

The TCD2903D is a high sensitive and low dark current 10680 elements x 3 line CCD color image sensor which includes CCD drive circuit and clamp circuit. The TCD2903D is a CCD (Charge-Coupled Device) linear image sensor manufactured by Toshiba. Below are its specifications, descriptions, and features based on the available knowledge:

### **Specifications:**  
- **Type:** Linear CCD Image Sensor  
- **Number of Pixels:** 7,500 (effective pixels)  
- **Pixel Size:** 7 µm (H) × 7 µm (V)  
- **Optical Black (OB) Pixels:** 51 (front) + 51 (rear)  
- **Dummy Pixels:** 12 (front) + 12 (rear)  
- **Total Pixels:** 7,626 (7,500 effective + 126 dummy/OB)  
- **Sensitivity:** High sensitivity in visible to near-infrared range  
- **Data Output:** 2-channel output (for high-speed readout)  
- **Clock Frequency:** Up to 20 MHz  
- **Supply Voltage:** +12 V (typical)  
- **Power Consumption:** Approximately 1.5 W (typical)  
- **Package:** 22-pin DIP (Dual In-line Package)  

### **Descriptions:**  
- The TCD2903D is designed for high-resolution scanning applications such as document scanners, facsimile machines, and industrial inspection systems.  
- It features a dual-output architecture to enable high-speed data transfer.  
- The sensor operates in a time-delayed integration (TDI) mode for improved sensitivity in motion applications.  

### **Features:**  
- **High Resolution:** 7,500 effective pixels for detailed image capture.  
- **Dual Outputs:** Two output channels for faster readout speeds.  
- **Low Noise:** Designed for high signal-to-noise ratio (SNR).  
- **Wide Spectral Response:** Sensitive in visible and near-infrared (NIR) ranges.  
- **Built-in Optical Black (OB) Pixels:** For dark-level reference.  
- **Compact Package:** 22-pin DIP for easy integration.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics and timing diagrams, refer to the official Toshiba datasheet.
