Product description

iC-LFH Series are integrating light-to-voltage converters with 1024/960/640/320 pixels pitched at 12.7 µm (center-to-center distance). Each pixel consists of a 12.7 µm x 600 µm photodiode, an integration capacitor, and a sample-and-hold circuit.

The control logic makes operation very easy, with only a start and clock signal necessary. A third input (ESH) optionally controls the
asynchronous, global shutter.

iC-LFHxxx is suitable for high pixel clock rates of up to 5 MHz.


  • 1024/960/640/320 active photo pixels with 12.7 µm x 600 µm (2000 DPI)
