GENERAL DESCRIPTION

The ADP8860SHIELD-EVALZ and the ADP8861SHIELD-EVALZ
incorporate light emitting diodes (LEDs) for quick and easy
evaluation of the ADP8860 and the ADP8861. Note that only the
ADP8860SHIELD-EVALZ has dual light intensity sensors. The
ADP8860SHIELD-EVALZ and the ADP8861SHIELD-EVALZ
follow the form factor of a regular Arduino® shield to allow
compatibility with microcontroller boards that use the same
interface. These evaluation boards also incorporate a separate
header dedicated to I
The ADP8860 and the ADP8861 are 7-channel LED drivers
that utilizes a charge pump with selective gain for maximum
efficiency. The LEDs driven by either device are programmable for
maximum current and fade in and out times via the I
Only the ADP8860 has a programable light intensity threshold
that can be set via the I
can handle up to 30 mA (typical), except for the seventh channel,
which can handle 60 mA (typical). Each channel can be unified
to have the same fade in time and fade out time, or each channel
can have an individual fade in time and fade out time for
greater flexibility
For full details on the ADP8860 and the ADP8861, see the
ADP8860 and the ADP8861 data sheets, which should be
consulted in conjunction with this user guide when using
these evaluation boards.
