300 DPI linear sensor array with hold

Product Features

• 102 x 1 Sensor Array
• 300 DPI
• High speed operation, up to 2 MHz
• High sensitivity
• Characterized for operation from 0°C to 70°C

The TSL1301 is a 300 dots-per-inch (DPI) CMOS linear sensor array. It consists of a 102 x 1 array of photodiodes with associated charge amplifier circuitry and a pixel data hold function that provides simultaneous integration start and stop times for all pixels. Operation is simplified by internal logic requiring only a serial-input pulse and a clock.

A cost-effective device, the TSL1301 is designed for a wide variety of applications such as mark and code reading, optical character recognition (OCR), contact imaging, edge detection, edge positioning, and optical encoding.

The TSL1301 offers high sensitivity (saturation exposure 7 nJ/cm2 at 565 nm wavelength) for a faster scan rate, lower cost illumination, and higher signal-to-noise ratio (SNR). With its low noise, low pixel response non-uniformity (PRNU), and low non-linearity, the TSL1301 is sufficient for 256 gray-scale (8-bit) applications. The device also features synchronous integration to minimize image skewing.

This device is targeted for high speed and cost sensitive applications such as scanners, bar code readers, and paper currency readers. Compared to compatible charge-coupled-device (CCD) solutions, the TSL1301 is a user friendly, low cost device. Other benefits include:

• Output referenced to ground – reduced circuit design for simplified layout
• Low image lag, 0.5% typ – enhanced system performance for high speed applications
• Single 5-V supply – simplified design for ease of use

The TSL1301 is available in the 8-pin clear DIP.
