grammed remotely via a network or even over the Internet. This type of device is per-

fect for manufacturers of potted/sealed assemblies, where trimming or fine calibration

is required, or it can be programmed remotely for applications involving hazardous

environments or remote locations. The gate threshold voltage can be trimmed, set,

and left in a one-time calibration type of application, or it can be increased several

times (see Figure 9.14). Once set, the gate threshold setting cannot be reduced or

cleared. However, bidirectional adjustments can be made simply ...
