Datasheet for the TSL1401CL linear sensor array with 128 pixels, charge amplifiers, and pixel data-hold function.
The TSL1401CL is a 128 × 1 linear sensor array with integrated charge amplifiers and a pixel data-hold function. It operates on a single 3V to 5V supply and requires only a serial input and clock for control. The device offers a wide dynamic range of 4000:1, rail-to-rail output, and low image lag of 0.5% typical. It is designed for applications like image scanning, OCR, and optical encoding.
Key features include 3524.3 μm² per pixel, 8μm pixel spacing, and a 400 DPI sensor pitch. The output is referenced to ground and does not require an external load resistor. The datasheet includes pin assignments, electrical characteristics, timing diagrams, and absolute maximum ratings.
