General Notes
When driving capacitive loads or shielded cables of greater
than 50pF remove the jumper for R11 and insert a 470 ohm
resistor. This will prevent oscillation that will appear as an
unstable DC offset to most measuring equipment.
The minimum value of load resistance is 2k ohms for a rated
output swing of ±10 Volts. The external load must be considered
along with the feedback resistance for the total load. For
reduced swings the output load can be increased up to a
maximum of 5 mA peak.
For optimum DC stability use single point “Star” grounds to
Pin B. This will prevent unwanted ground loops or “unexplained”
DC offsets.
When the MK150 is wired in a system and it appears that
something is wrong, remove the MK150 and test it individually
to make sure that it functions as expected. Then troubleshoot
the system from the transducer to the end, a function block
at a time.
If a high precision amplifier is required with a gain of 100 or
more, the 176/178 Instrumentation amplifiers are a much
better choice for most systems.
If all else fails please feel free to call our applications
engineers; we spend time trouble shooting our own systems
and can sometimes spot trouble right away. We even learn
new tricks from our customers!
To order the MK150 for use with the 152, specify the MK150
as MK150-152. For use with the 155, specify the MK150 as
MK150-155.
