Description
The TH7888A is particularly designed for high data rate applications (up to 30 pic-
tures/second in 1024 x 1024 progressive scan format) in the medical and industrial
fields. This area array image sensor consists of a 1024 x 1024 pixels (14 µm x 14 µm)
image zone associated with a memory zone (masked with an optical shield). To
increase the data rate, two separate outputs are provided, which can be used for par-
allel readout (the readout frequency is up to 20 MHz/output, leading to a total readout
frequency of 40 MHz). These two outputs allow three readout modes (single or dual
port). The TH7888A is designed with an antiblooming structure which provides an
electronic shutter capability. Moreover, the 2 x 2 binning mode is available on this sen-
sor, providing an image size of 512 x 512 pixels with 28 µm x 28 µm pixels. The
TH7888A package is sealed with a specific anti-reflective window optimized in the 400
- 700 nm spectrum bandwidth on the sealed version.
