Description and Introduction

The TCD2561D is a high sensitive and low dark current 5340 elements ?4 line CCD color image sensor which includes CCD drive circuit, clamp circuit. The TCD2561D is a CCD (Charge-Coupled Device) linear image sensor manufactured by Toshiba. Below are the key specifications, descriptions, and features based on available factual information:

### **Specifications:**  
- **Type:** Linear image sensor (CCD)  
- **Number of Pixels:** 5,000 pixels (effective)  
- **Pixel Size:** 7 μm (H) × 7 μm (V)  
- **Total Pixel Length:** 35 mm  
- **Spectral Response Range:** 400 nm to 1,000 nm (visible to near-infrared)  
- **Output Signal:** Analog (2-phase output)  
- **Clock Frequency:** Up to 2 MHz (typical)  
- **Supply Voltage:** +12 V (typical for driving)  
- **Operating Temperature Range:** -10°C to +60°C  
- **Package:** Ceramic DIP (Dual In-line Package)  

### **Descriptions:**  
- Designed for high-resolution scanning applications such as document scanners, optical measurement systems, and industrial inspection equipment.  
- Features a built-in sample-and-hold circuit for stable signal output.  
- Includes a light-shielded dummy pixel section for dark-level reference.  

### **Features:**  
- **High Sensitivity:** Suitable for low-light conditions due to efficient charge transfer.  
- **Low Noise:** Improved signal-to-noise ratio (SNR) for accurate imaging.  
- **Wide Dynamic Range:** Capable of handling varying light intensities.  
- **Monochrome Output:** Primarily used for grayscale imaging.  
- **Durable Construction:** Ceramic package ensures reliability in industrial environments.

Application Scenarios & Design Considerations

The TCD2561D is a high sensitive and low dark current 5340 elements ?4 line CCD color image sensor which includes CCD drive circuit, clamp circuit.

Alternative Part Number

  • ILX511B --: Linear CCD image sensor with comparable 2048-pixel resolution and pin-compatible analog output, widely used as a drop-in replacement in scanner and sensor designs.
  • TCD1304DG --: Same Toshiba CCD family with similar 3648-pixel linear array and 5V operation; closest electrical and timing match for designs originally using the TCD2561D.
  • ELIS-1024 --: Linear CCD sensor offering similar spectral response and clocking scheme, suitable when a lower-resolution alternative with simpler drive requirements is acceptable.
  • ILX554B --: Linear CCD sensor offering similar resolution and supply requirements, suitable as a functional substitute where minor timing adjustments are acceptable.
