Figure 12. A Single-Supply RTD Amplifier
Amplifiers A2 and A3 are configured in a two op amp instru-
mentation amplifier configuration. For ease of measurement,
the IA resistors are chosen to produce a gain of 259, so that
each 1
°C increase in temperature results in a 10 mV increase in
the output voltage. To reduce measurement noise, the band-
width of the amplifier is limited. A 0.1
F capacitor, connected
in parallel with the 100 k
resistor on amplifier A3, creates a
pole at 16 Hz.
