General Description

PAC7640 is a global shutter image sensor with enhanced Quantum Efficiency (QE) in the NIR region. PAC7640 is well suited for applications where conservation of NIR LED power is critical. It features 400×400 resolution with image capture capability of 120 frame per second (fps) at full resolution.

The sensor comes with an integrated image sensor ISP. In addition, the PAC7640 also allows for multiple camera synchronization, which makes it suitable for 3D stereo type applications. All ISP functionalities can be controlled through register settings via I2C.
