Detailed Description
As shown in Figure 1, most applications of the MX581
require no external components. Connections are +VS,
VOUT, and GND (GND is tied to the case in the TO-5
package). Usually the desired accuracy is obtained by
selecting the appropriate device grade. However, any
part can be adjusted to a tighter tolerance, or to slightly
different voltage, using the fine trim circuit in Figure 2.
The table in Figure 2 lists the trim range for different
values of R in the figure, and also shows the effect on
temperature coefficient.
