LONDON CMOS image sensor specialist OmniVision Technologies, Inc. has started sampling a 1/18-inch sensor targeted at medical diagnostic applications.
Dubbed the OV6920, the company says the part is the smallest in its range of CameraChip products to date, and the smallest such sensor from any source.
The 2.1 mm by 2.3 mm CSP packaged chip will enable a 3.2 mm diameter microscopic camera module, making many medical procedures even less invasive. The company says the device will also allow devices such as intubation systems and endoscopes to be made even smaller to allow for use on infants and small children.
OmniVisions's previously smallest camera chip measured 1/7-inch, and the company says the closest thing in the market today is a 1/12-inch CCD. According to Hasan Gadjali, OmniVision's Vice President for Advanced Products: "Several customers are already evaluating samples and are very excited about the possibilities this small camera can offer."
The ultra small, single chip OV6920 only needs a clock and power to get the NTSC composite signal out for direct interface with a VCR/TV/monitor, and needs only a single 3.3-volt DC supply.
