DESCRIPTION
iC-LA is an integrating light-to-voltage converter with a row of 64 separate pixels. Each pixel consists of one photodiode, an integration capacitor and a track-and-hold circuit. For each pixel the photocurrent of the photodiode charges the integration capacitor. The track-and-hold circuit reads out the capacitor voltage in track mode; when the circuit switches into hold mode this voltage is present for one clock cycle at output AOUT.
