PAC7640: Enhanced QE Global Shutter Image Sensor

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 400x400 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
