8.2.6 Single-Supply Operation of the ISO124 Isolation Amplifier
The circuit shown in Figure 21 uses a 5.1-V Zener diode to generate the negative supply for an ISO12x from a single supply on the high-voltage side of the isolation amplifier. The input measuring range will be dependent on the applied voltage as noted in the accompanying table.
NOTE:
Because the amplifier is unity gain, the input range is also the output range. The output can go to –2 V because the output section of the ISO amp operates from dual supplies.For additional information see Single-Supply Operation of Isolation Amplifiers.
