Description
The TH7887A is especially designed for high data rate applications (up to 60 pict/s) in
medical and industrial fields.
This area array image sensor consists of a 1024 x 1024 pixels (14 µ m x 14 µ m) image
zone associated to a memory zone (masked with optical shield).
In order to increase data rate, the image zone is divided into four zones (256 x 1024
each) which are read in parallel through 4 different outputs (readout frequency up to
20 MHz/output leading to a total readout frequency of 80 MHz).
The TH7887A is designed with antiblooming gates.
Moreover, the 2 x 2 binning mode is available on this sensor. In this case, the image
size is 512 x 512 with 28
µ m x 28 µ m pixels. Each output will read 128 x 512 pixels.
The TH7887A is sealed with a specific anti-reflective window optimized in 400 -
700 nm bandwidth.
