Product Information

Back to top
iC-LFM is an integrating light-to-voltage converter with a single line of 64 pixels pitched at 63.5μm (center-to-center distance). 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 paused at any time (electronic shutter).

With the start signal 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 64 clock pulses.

iC-LFM 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.
