Product Summary

The TSL1401R-LF is a linear sensor array. The TSL1401R-LF consists of a 128 × 1 array of photodiodes, associated charge amplifier circuitry, and an internal pixel data-hold function that provides simultaneous-integration start and stop times for all pixels. The pixels measure 63.5 μm (H) by 55.5 μm (W) with 63.5-μm center-to-center spacing and 8-μm spacing between pixels. Operation is simplified by internal control logic that requires only a serial-input (SI) signal and a clock.

Parametrics
