Figure 20. Kelvin Connection Reference Using an Operational Amplifier
With Unlimited Capacitive Load Drive Capability
Figure 21 shows a circuit using a dual operational amplifier with unlimited capacitive load drive. The operational
amplifier should provide stable 3.6 V and 1.6 V reference voltages for REFTF and REFBF, respectively. The
amplifier must be able to maintain stability while driving unlimited capacitive loads, so the 0.1
F capacitors C1
and C2 can connect directly to the outputs of the operational amplifiers, which reduces high frequency
transients. Capacitors C3 and C4 shunt across the internal resistors of the force-sense connections and prevent
instability. The stability of any operational amplifier used must be examined closely when driving capacitive
loads.
