Product Information

Back to top
iC-LFL1402 is an integrating light-to-voltage converter with a single line of 256 pixels pitched at 63.5μm (center-to-center distance). Due to the
monolithical integration there is no pixel-gap or pitch distortion whatsoever. Each pixel consists of a 56.4μm x 200μm photodiode, an integration capacitor and a sample and hold circuit.

The integrated control logic makes operation very simple, with only a start and clock signal necessary. A third control input enables the integration period to be prematurely terminated at any time (electronic
shutter).

When the start signal is given the hold mode is activated for all pixels simultaneously with the next rising clock edge; starting with pixel 1 the hold voltages are switched in sequence to the push-pull output amplifier. The second clock pulse deletes all integration capacitors and the integration period starts again in the background during the output phase. A run is complete after 256 clock pulses.

iC-LFL1402 is suitable for high clock rates of up to 5 MHz. If this is not required the supply current can be reduced via the external bias setting.
