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 µm x 14 µm) 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 µm x 28 µm 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.
