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).
In addition to the configurations described above, the 7021/7023 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 effective
controlrange of the analog input signal.
In all cases, the LEDs being driven should be located as close to the 7021/7023 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 7023 part number may be used, which is supplied with 6” colored leads.
