The input filter also performs an important reliability function—it reduces transient spikes from ESD events flowing through the acpo sensing resistor. 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 782g path for pF Note for the Voltage Divider: Hi everyone, I hope I’m posting in the right part of the forum.

ACPL-782T problem understanding datasheet

ACPLT problem understanding datasheet. Because of the Kelvin connection, any voltage drops across the leads carrying the load current should have no impact on the measured voltage. If a dedicated supply is required, in many cases it is possible to add an additional winding on an existing transformer.

RoHS Certificate of Compliance. A differential output voltage is created on the other side of the ACPLT optical isolation barrier. Specifications are within the Recommended Operating Conditions. Propagation Delay Test Circuits. Media New media New comments Search media. An inexpensive 78L05 three-terminal regulator can also be used to reduce the floating supply voltage to 5 V.

Typical values represent the mean value of all characterization units at the ac;l operating conditions. You agree that the Information as provided here by RS may not be error-free, accurate or up-to-date and that it is not advice. Thank you for your feedback.

Each In a Tube of Started by fastline Yesterday at 8: In addition, the op-amp should scpl have enough bandwidth and slew rate so that it does not adversely affect the response speed of the overall circuit. 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.


Insulation characteristics are guaranteed only within the safety maximum ratings which must be ensured by protective circuits within the application. The maximum value of the sense resistor is determined by the current being measured and the maximum recommended input voltage of the isolation amplifier.

This test mode is for testing LED coupling and is not intended for customer use. Save to an existing qcpl list Save to a new parts list.

Replacing a 4 pin leaded inductor with a 2 pin Started 78t2 gkmaia Yesterday at The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-output continuous voltage rating. When sensing currents large enough to cause significant heating of the sense resistor, the temperature coefficient tempco of the resistor can introduce nonlinearity due to the signal dependent temperature rise of the resistor. The product can also be used for general analog signal isolation applications requiring high accuracy, stability, and linearity under similarly severe noise conditions.

The power supply for the ACPL T is most often obtained from the same supply used to power the power transistor gate drive circuit. Allowing you to reduce waste and improve production efficiency. The foregoing information relates to product sold on, or after, the date shown below.

Short circuit current is the amount of output current generated when either output is shorted to VDD2 or ground. However, the output supply current will continue to rise for differential input voltages up to approximately mV, beyond which the output supply current remains constant. Input Offset Voltage vs. The magnitude of the output quantization noise is very small at lower frequencies below 10kHz and increases with increasing frequency.


Output Side The op-amp used in the external post-amplifier circuit should be of sufficiently high precision so that it does not contribute a significant amount of offset or offset drift relative to the contribution from the isolation amplifier. By referencing the input circuit to the negative side of the sense resistor, any load current induced noise transients on the resistor are seen as a common-mode signal and will not interfere with the current-sense signal.

The product does not contain any of the restricted substances in concentrations and applications banned by the Directive, and for components, the product is capable of being worked on at the higher temperatures required by lead—free soldering. On page 16 of the datasheet is the recommended circuit for voltage sensing application I want to stick to it. The product does not contain any of the restricted substances in concentrations and applications banned by the Directive, and for components, the product is capable of being worked on at the higher temperatures required by lead—free soldering.

The bypass capacitors are required because of the high-speed digital nature of the signals inside the ACPLT. Output noise comes from two primary sources: Sending feedback, please wait This effect can be minimized by reducing the thermal resistance of the current sensing resistor or by using a resistor with a lower tempco.

This is the Absolute Value of Gain Change vs. The product detailed below complies with the specifications published by RS Components. 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.

The ACPLT utilizes sigma delta 6′ analog-to-digital converter technology, chopper stabilized amplifiers, and a fully differential circuit topology. A gull-wing surface mount option E is also available.
