ACPL-782T problem understanding datasheet
You must log in or register to reply here. Recommended circuit for temperature sensing application. In addition, the op-amp should also have enough bandwidth and slew rate so that it does not adversely affect the response speed of the overall circuit. The Kelvin connections to the resistor should be brought together under the body of the resistor and then run very close to each other to the input of the ACPLT; this minimizes the loop area of the connection and reduces the possibility of stray magnetic fields from interfering with the measured signal.
The product can also be used for general analog signal isolation applications requiring high accuracy, stability, and linearity under similarly severe noise conditions. As the resistance value is reduced, the output voltage across the resistor is also reduced, which means that the offset and noise, which are fixed, become a larger percentage of the signal amplitude.
On page 16 of the datasheet is the recommended circuit for voltage sensing application I want to stick to it. 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.
Refer to the following figure for dependence of PS and IS on ambient temperature. The foregoing information relates to product sold on, or after, the date shown below. Also, multiple layers of the PC board can be used to increase current carrying capacity. Avago R2Coupler isolation products provide the reinforced insulation and reliability needed for critical in automotive and high temperature industrial applications.

Chopper noise results from chopper stabilization of the output op-amps. Components are supplied in the original manufacturer’s packaging, ready for insertion into your machinery.
The selected value of the sense resistor will acppl somewhere between the minimum and maximum values, depending on the particular requirements of a specific design.
The effect increases as the resistor-to-ambient thermal resistance increases. Because of the switched-capacitor nature of the input sigma-delta converter, time-averaged values are shown. Save to an existing parts list Save to a new parts list. Floating lead protrusion is 0. The only direct connection between the ACPLT circuit and the gate drive circuit should be the positive power supply line. A filter circuit can be easily added to the external post-amplifier to reduce the total RMS output noise.

Welcome to our site! If the power dissipation in the sense resistor is too high, the resistance can be decreased below the maximum value to decrease power dissipation.
Lowering the thermal resistance can be accomplished by repositioning the current sensing resistor on the PC board, by using larger PC board traces to carry away more heat, or by using a heat sink. For product information and a complete list of distributors, please go to our web site: What is Production Packaging? This performance is delivered in a compact, auto-insertable, industry standard 8-pin DIP package that meets worldwide regulatory safety standards. The product detailed below complies with the specifications published by RS Components.

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. AVEN – March 23, Each In a Tube of If the sense resistor is not located on the same PC board as the ACPLT circuit, a tightly twisted pair of wires can accomplish the same thing.
