How to design an inexpensive HART transmitter By Thomas Kugelstadt Applications Manager
... Making R8 to R11 equal in value simplifies this equation to VOUT = VREF + VDC − VHART . Because VHART consists of a 200-mV trapezoid swinging symmetrically about VREF, the output of A2 contains only the small HART waveform riding on the variable DC level. Feeding VOUT into TI’s XTR115 voltage-to-cur ...
