General Description
The PixArt PAW3805EK-CJV1 is an optical sensor which
is
optimized for infrared (IR) LED based wireless
mouse
application. It has high accuracy navigation ability
that
enables navigation virtually on any flat surface,
including
the transparent glass. The low power architecture
and
automatic power management make it suitable for
power-sensitive application such as a wireless
mouse.
PAW3805EK-CJV1 is capable of high-speed motion
detection up to the velocity of 40 inches/sec and 10g
on
non-glass surfaces, 20 inches/sec and acceleration of
5g
on glass surface. In addition, it has an on-chip
oscillator
and a built-in programmable LED current driver. In
order
to achieve the best tracking performance, it is
recommended to match the sensor with L029-LSI
optical
lens.
