400-DPI linear image sensor

The TSL1401 linear image sensor provides a high pixel density of 400 dots per inch, a maximum clock speed of 2 MHz, and excellent linearity and uniformity characteristics. As a result, the device is well-suited for applications such as contact image scanning, rotary and linear encoding, edge detection and level sensing.

The TSL1401 provides a great deal of control over pixel integration. A new hold function helps eliminate image skewing by starting and stopping integration of all pixels simultaneously. In addition, the clock can be gated to provide an electronic shutter for applications, such as those with targets moving at high speeds, where there is need for fine control over the exposure period of the pixels.
