iC-LA 64X1 LINEAR IMAGE SENSOR Rev A3, Page 2/8 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. Photocurrent integration is started simultaneously for all pixels with the rising edge of the...

iC-LA 64X1 LINEAR IMAGE SENSOR Rev A3, Page 7/8 Fig. 4: timing diagram DESCRIPTION OF FUNCTIONS In the following description it is assumed that DNU is set to lo. If a hi pulse is available at DIN, integration operation of iC-LA is initiated with the next rising edge of the CLK clock signal. During the first clock cycle all integration capacitors are discharged with the falling edge at CLK. In this clock cycle the chip temperature is output at AOUT. In the second clock cycle all integration capacitors are precharged to VCMIN; with the falling edge of the clock signal all 64 pixels start to...
