TH7422B
NEAR INFRARED InGaAs LINEAR SENSOR
300 PIXELS
DESCRIPTION
This device is based on a 300 InGaAs photodiode linear
array, with a 26µm pitch, using an in line pixel layout.
Two 150:1 CCD multiplexors chips, offering memory and
delayed 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.
This device is also available in a full CMOS interface ver-
sion : TH 74KA22B or TH 74KB22B.
