TH7426A/27A
NEAR INFRARED InGaAs LINEAR IMAGE SENSOR
300 PIXELS
DESCRIPTION
These devices are based on a 300 InGaAs photodiode li-
near array, with a 26µm pitch, using an in line pixel layout or
a staggered pixel layout.
Two 150:1 CCD multiplexor chips, offering memory and de-
layed readout capability, are hybridized on both sides of the
photodiode array so as to build a complete module.
Specially designed to allow an accurate butting, those mo-
dules could be tied together on request so as to provide an
array extension with only one dead pixel at the splice.
These devices are also available in a full CMOS interface
version :
TH74KA26A/TH74KA27A or TH74KB26A/TH74KB27A.
