Product Overview
The TCD1209DG is a high-sensitivity, low dark current 2048-element linear CCD image sensor from Toshiba, optimized for high-resolution document scanners, industrial line-scan inspection and spectroscopic testing. It converts light signals to precise analog voltage output, featuring a single-row photodiode array with 14μm pixel pitch for high spatial resolution and stable MTF performance.
This sensor integrates an on-chip electronic shutter and sample-and-hold circuit, simplifying peripheral circuit design and stabilizing output signals. It operates with 5V CMOS clock signals and 12V typical power supply, compatible with mainstream MCUs and DSP controllers. The hermetic 22-pin ceramic dual inline package with protective glass window delivers long-term stability for precision optical equipment.
Core Advantages
Integrated Electronic Shutter System
Built-in software adjustable electronic shutter supports flexible exposure time tuning, effectively avoiding signal saturation under high or fluctuating lighting conditions.
On-Chip Sample-and-Hold Circuitry
Internal sample-and-hold module locks analog output signals, generating smooth continuous video waveform and eliminating the need for external discrete filter circuits.
Ultra-Low Dark Current & High SNR
Adopting Toshiba advanced semiconductor process to suppress dark current and pixel noise, maintaining clear analog signal output even under low-light test environments.
Simplified 5V CMOS Clock Drive
Only standard 5V CMOS clock signals are required for operation, reducing MCU IO resource occupation and shortening hardware firmware development cycles.

Frequently Asked Questions
Q1: Are all stocked TCD1209DG sensors original Toshiba new parts?
A: All TCD1209DG linear CCDs are 100% brand-new genuine Toshiba factory stock. Every batch undergoes strict incoming QC and lot traceability inspection. Devices are sealed in anti-static tubes to prevent scratches and contamination on ceramic packaging and optical glass.
Q2: What benefits does the CERDIP hermetic package bring to this linear sensor?
A: The 22-pin ceramic CERDIP package features outstanding thermal stability and long-term airtight sealing, far better than plastic packages. Ceramic material avoids pixel offset drift caused by thermal expansion, while built-in anti-reflective glass maximizes light transmittance for the 2048 photodiode array.
Q3: How do the built-in electronic shutter and sample-and-hold circuits simplify hardware design?
A: Conventional linear CCDs require extra peripheral circuits to control exposure and smooth analog signals. The TCD1209DG integrates both modules on-chip. Exposure time is adjusted by simple logic signals, and sample-and-hold outputs stable waveforms that connect to ADC chips without extra filter circuits.
Q4: How can I get official timing diagrams and bulk pricing offers?
A: Fill out the page inquiry form with your project information and order quantity. Our optical sensor technical team will send complete datasheets, clock timing charts and customized bulk discounts within 24 working hours.
