This test mode is for testing LED coupling and is not intended for customer use. The datasheet says it has a gain of 8 page 6 So this is what I understand: Acp are supplied in the original manufacturer’s packaging, ready for insertion into your machinery.

Sending feedback, please wait Minimum External Tracking Creepage L 8. Short circuit current is the amount of output current generated when either output is shorted to VDD2 or ground. Because of the Kelvin connection, any voltage drops across the leads carrying the load current should have no impact on the measured voltage.

Although the application circuit is relatively simple, a few recommendations should be followed to ensure optimal performance. Resistor networks can be used that have much better ratio tolerances than can be achieved using discrete resistors. The maximum average power dissipation in the sense resistor can also be 872t calculated by multiplying the sense resistance times the square of the maximum RMS accpl, which is about 1 W in the previous example.

CMRR is defined as the ratio of the differential signal gain signal applied differentially between pins 2 and 3 to the common-mode gain input pins tied together and the signal applied to both inputs at the same timeexpressed in dB. Temperature in PPM level. To obtain optimal CMTI performance, the layout of the PC board should minimize any stray coupling by maintaining the maximum possible distance between the input and output sides of the circuit and ensuring that any ground or power plane on the PC board does not pass directly below or extend much wider than the body of the ACPLT.

Adpl the resistance value is reduced, the output voltage across the resistor is also reduced, which means that the ac;l and noise, which are fixed, become a larger percentage of the signal amplitude. If the power dissipation in the sense resistor is too high, the resistance can be decreased below the maximum value to decrease power dissipation. Contact your Avago sales representative or authorized distributor for information.

Articles Top Articles Search resources. Choosing a particular value for the resistor is usually a compromise between minimizing power dissipation and maximizing accuracy. A differential output voltage is created on the other side of the ACPLT optical isolation barrier.

This differential output voltage is proportional to the motor current and can be converted to a single-ended signal by using an op-amp as shown in the recommended application circuit. Just saying hello Started by MichaelaJoy Yesterday at 6: Typical drift specifications are determined by calculating the rate of change of the specified parameter versus the drift parameter at nominal operating conditions for each characterization unit, and then averaging the individual unit rates.

The effect increases as the resistor-to-ambient thermal resistance increases.

This has two primary effects on resistor accuracy. Save to parts list Save to parts list. Each In a Tube of The product apl also be used for general analog signal isolation applications requiring high accuracy, stability, and linearity under similarly severe noise conditions.

Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Input Offset Voltage vs. The only direct connection between the ACPLT circuit and the gate drive circuit should be the positive power supply line.

Started by fastline Yesterday at 8: First, the effective resistance of the sense resistor can become dependent on factors such as how long the leads are, how they are bent, how far they are inserted into the board, and how far solder wicks up the leads during assembly these issues will be discussed in more detail shortly. The Manufacturers and RS reserve the right to change this Information at any time without notice.

If the same power supply is used both for the gate drive circuit and for the current sensing circuit, it is very important that the connection from GND1 of the ACPLT to the sense resistor be the only return path for pF Note for the Voltage Divider: The high impedance characteristic of the input terminals of ACPLT helps in determining those resistors value since one can select relatively high resistance of R2 and R3 and R1 can be determined easily.
