amplifiers ISO122P / 124 low-cost isolation amplifier and HPR117 DC / DC converter component provides the required isolation amplifier primary and secondary side of the power supply by the two HPR117, isolated ISO122 completion signal amplification, Meanwhile HPR117 of O, feet form a + 15V (for Gnd) power output. Because HPR117 built 0.33 F bypass capacitor, so no external power supply terminal of each bypass capacitor filter. The characteristics of the circuit can be eliminated due to power supply noise, improve the power supply rejection ratio.
