Microprocessor Control
Figure 16 shows a typical interface for a Microchip PIC® or similar µcontroller. The reference output provides the
operating voltage for the processor (5V at up to 20mA current).
Other Control Applications
In addition to the con gurations described above, the 3021/3023 may also be driven by a D to A converter. As in
the cases above, the analog control signal should have its ground common to LED-. Figure 2 shows the e ective
control range of the analog input signal.
Connections
In all cases, the LEDs being driven should be located as close to the 3021/3023 LED output as possible. When the
use of long leads is required, use heavier gauge wire. For strobe or pulse applications, a wire length not
exceeding 6" should be used to maintain accurate timing.
The power input wires/traces should also be kept short. Where DC input units are located more than 18" from the
source, a 220µF, 50V capacitor should be placed across the input terminals as shown in Figure 18.
For applications where the use of header pins is inconvenient, a mating connector with 6" leads is available as an
accessory, or the 3023 part number may be used, which is supplied with 6” colored leads.
