BENEFITS
• Precision matched electrically after packaging
• Simple, elegant single-chip user option
to trimming voltage/current values
• Excellent device matching characteristics with
or without additional electrical trim
• Remotely and electrically trim parameters on
circuits that are physically inaccessible
• Usable in environmentally sealed circuits
• No mechanical moving parts -- high G-shock
tolerance
• Improved reliability, dependability, dust and
moisture resistance
• Cost and labor savings
• Small footprint for high board density
applications
