Shutdown and Short Circuit Current Limit
Set both DAC inputs low to shut down the device. Built-in
short circuit protection limits the supply current to a maxi-
mum of 50mA.
Digital Control
A digital-to-analog converter (DAC) allows selection of the
following modes: OFF, 7mA, 14mA, 20mA, per diode.
By turning the IN B pin ON and OFF, the current can be
modulated between 7 to 20mA to achieve any I
(PWM). In PWM mode, the modulating frequency has to be
set sufficiently high in order to avoid a flickering effect
(100Hz to 1kHz).
Average
value
Digital Control with PWM
Any input can be modulated by a pulse train of variable duty
cycle (
δ
). By turning ON and OFF DAC inputs A or B, the
current can be continuously modulated to any average value
between 1 to 19mA. For a maximum range of LED current,
both A&B can be modulated at the same time.
