Potentiometer Questions Started by norbss Yesterday at Data subject to change. Output Side The op-amp used in the accpl 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.
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.
Contact your Avago sales representative or authorized distributor for information.
Please select an existing parts list. This is the Absolute Value of Gain Change vs. Note that the typical drift specifications in the tables below may differ from the slopes of the mean curves shown in the corresponding figures. The Manufacturers reserve the right to change this Information at any time without notice.
Tolerances unless otherwise specified: The maximum value of the sense resistor is determined by the current being measured and the maximum recommended input voltage of the isolation amplifier. PC Board Qcpl The design of the printed circuit board PCB should follow good layout practices, such as keeping bypass capacitors close to the supply pins, keeping output signals away from input signals, the use of ground and power planes, etc.
This performance is delivered in a compact, auto-insertable, industry standard 8-pin DIP package that meets worldwide regulatory safety standards. 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.
The Manufacturers and RS reserve the right to change this Information at any time without notice. Input Offset Voltage vs. You have chosen to save the following item to a parts list:. This test mode is for testing LED coupling and is not intended for customer use. Save to parts list Save to parts list. Welcome to our site! This effect can be minimized by reducing the thermal resistance of the current sensing resistor or by using a resistor with a lower tempco.
You must log in or register to reply here. The datasheet says it has a gain of 8 page 6 So this is what I understand: Input Offset Voltage Test Circuit. If the same power acppl 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 apcl path for pF Note for the Voltage Divider: The maximum average power dissipation in the sense resistor can also be easily calculated by multiplying the sense resistance times the square of the maximum RMS current, which is about 1 W in the previous example.

A filter circuit can be easily added to the external 7822t to reduce the total RMS output noise. Save this item to a new parts list. The postamplifier circuit includes a pair of capacitors C5 and C6 that form a single-pole low-pass filter; these capacitors allow the bandwidth of the post-amp to be adjusted independently of the gain and are useful for reducing the output noise from the isolation amplifier.
A floating power supply which in many applications could be the same supply that is used to drive the high-side power transistor is regulated to 5 V using a simple zener diode D1 ; the value of resistor R4 should be chosen to supply sufficient current from the existing floating supply.
On page 16 of the datasheet is the recommended circuit for voltage sensing application I want to stick to it. Recommended Supply and Sense Resistor Connections. 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. Wcpl feedback, please wait Motor Output Horsepower vs. A differential output voltage is created on the other side of the ACPLT optical isolation barrier.

Axpl a two-terminal current sensing resistor, as the value of resistance decreases, the resistance of the leads become a significant percentage of the total resistance. The ACPLT utilizes sigma delta 6′ analog-to-digital converter technology, chopper stabilized amplifiers, and a fully differential circuit topology.
