Typical Applications
4 mA-20 mA Two Wire Current Transmitter
TL/H/5609–20
The LM329 reference provides excellent line regulation and gain stability. When bridge is balanced
(I
OUT
e
4 mA), there’s no drop across R3 and R4, so that gain and offset adjustments are non-in-
teractive. The LM334 configured as a zero-TC current source supplies quiescent current to circuit.
R11 provides current limiting.
