available in
a lead-free
package
The OV7955 is a low-cost, high-performance analog
and digital image sensor designed specifically for
mainstream automotive applications. The AEC-Q100
Grade 2 qualified OV7955 offers superior low-light
sensitivity in an ultra-compact module size, making it an
ideal camera solution for rear-view, surround-view and
blind spot detection systems.
Additionally, the OV7955 offers features new to the
automotive industry, including built-in memory for
initialization, which reduces a camera's overall bill of
materials and size. The crop and resize feature allows
the same camera module to be designed into virtually
any vehicle platform without requiring additional
mechanical adjustments.
Utilizing OmniVision's proprietary high-sensitivity
OmniPixel®3-HS pixel architecture, the sensor offers
industry-leading low-light sensitivity of 16 V/lux-sec
and excellent signal-to-noise-ratio (SNR).
The OV7955 features the industry's smallest AEC-Q100
qualified automotive package (a-CSP™), measuring only
5.7 x 5.4 mm, and offers an operating temperature range
of -40°C and 105°C.
