PTG
Programmable Transmit Gain - The 2-wire to 4-wire transmission gain is 0dB if this pin is left floating
and -6.02dB if tied to ground. The -6.02dB gain option is useful in systems where Pulse Metering is
used. See Figure 23.

CH
AC/DC Separation Capacitor - CH is required to properly process the AC current from the DC loop
current. Recommended value 0.1
F.

ZT
2-Wire Impedance Matching Pin - Impedance matching of the 2-wire side is accomplished by placing
an impedance between the ZT pin and ground. See Equation 32.
