LED DISPLAY DRIVER
16-BIT CONSTANT-CURRENT LED DRIVER
DESCRIPTION
AD5026 is a 16-channel, constant current sink
LED driver. It contains High-precision
current-drive circuit, 16-bit shift register, Latch
and temperature compensation circuit.
AD5026 provides users with great flexibility and
device performance in their system design for
LED display applications, e.g. LED panels.
AD5026 have the ability of the anti-static
technology and anti-jamming technology. It can
make chip data transmission more stable and
work more reliable. Chip antistatic ability up to
more than 4KV.
The AD5026 is available in SSOP24(0.635/1.0) &
QFN24 (4X4) Packages.
APPLICATION
Outdoor LED Video Display
Indoor LED Video Display
Message Signs
