LM9618 Monochrome CMOS Image Sensor VGA 30 FPS
General Description
Applications
The LM9618 is a high performance, low power, 1/3” VGA CMOS
Active Pixel Sensor capable of capturing grey-scale digital still or
motion images and converting them to a digital data stream.
f Security Cameras
f Machine Vision
f Automotive
f Biometrics
f IR imaging
In addition to the active pixel array, an on-chip 12 bit A/D conver-
tor, fixed pattern noise elimination circuits, a video gain and sep-
arate color gain are provided. Furthermore, an integrated
programmable smart timing and control circuit allows the user
maximum flexibility in adjusting integration time, active window
size, gain and frame rate. Various control, timing and power
modes are also provided.

Sample Kit
LM9618IEA
This kit includes 5 LM9618 samples and complete product datasheet.
LM9618SAMPLE-KIT
This is a small PCB that houses the LM9618 sensor together with all neces-
sary discrete components. The headboard is supplied with C-MOUNT lens
block (lens not included) and documentation. M12 Lens mounts (not
included) can be mounted on this board.
Headboard
LM9618HEADBOARD
LM9618EVAL-KIT
LM96XXLENS-KIT
The evaluation kit is a complete software/hardware solution designed to
give the system designer a complete raw data evaluation toolset for the
LM9618 sensor.
Evaluation Kit
The kit contains a LM9618 headboard (see above), C-MOUNT lens, capture
and display board, power supply, SNAPS EVAL version Windows applica-
tion software and documentation.
The 1/3” lens kit consists of four 1/3” M12 lenses and an M12 mount that
can be attached to any LM9618 headboard (see above). All lenses in the kit
have been tested by National Semiconductor and are supplied with docu-
mentation and test data.
