... The ACPL-796J is a 1-bit, second-order sigma-delta (6') modulator converts an analog input signal into a high- speed data stream with galvanic isolation based on optical coupling technology. The ACPL-796J operates from power supply with dynamic range with an appro- priate digital filter. The differential inputs of ±200 mV (full scale ± ...

... Analog Input The differential analog inputs of the ACPL-796J are im- plemented with a fully-differential, switched-capacitor circuit. The ACPL-796J accepts signal of ±200 mV (full scale ±320 mV), which is ideal for direct connection to shunt based current sensing or other low-level signal sources applications such as motor phase current measurement. ...

Shunt esistors The current-sensing shunt resistor should have low re- sistance (to minimize power dissipation), low inductance (to minimize di/dt induced voltage spikes which could adversely affect operation), and reasonable tolerance (to maintain overall circuit accuracy). Choosing a particu- lar ...

... HV– Figure 0. Schematic for three conductor shunt connection. oltage Sensing The ACPL-796J can also be used to isolate signals with am- plitudes larger than its recommended input range with the use of a resistive voltage divider at its input. The only restrictions are that the impedance of the divider be rela- tively small (less than 1 k:) so that the input resistance (33 k:) and input bias current (0 ...
