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. The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-output continuous voltage rating.
A filter 782tt can be easily added to the external post-amplifier to reduce the total RMS output noise. Nonlinearity is defined as half of the peak-to-peak output deviation from the best-fit acppl line, expressed as a percentage of the full-scale differential output voltage.
RoHS Certificate of Compliance. 782r datasheet says it has a gain of 8 page 6 So this is acll I understand: Avago R2Coupler isolation products provide the reinforced insulation and reliability needed for critical in automotive and high temperature industrial applications. Because of the switched-capacitor nature of the input sigma-delta converter, time-averaged values are shown.
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 rise time of the test waveform is set to approximately 50 ns.

PC Board Layout The design of the printed circuit board PCB should follow good layout practices, such as keeping bypass capacitors close 78t the supply pins, keeping output signals away from input signals, the use of ground and power planes, etc.
Please enter a message. Resistance of thermistor RL: When the differential input signal exceeds approximately mV, the outputs will limit at the typical values shown. This test mode is for testing LED coupling and is not intended for customer use. In a typical implementation, and motor currents flow through an external resistor and the 782 analog voltage drop is sensed by the ACPLT.
This is a two-terminal measurement: This is the Absolute Value of Gain Change vs. 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.

Articles Top Articles Search resources. This effect can be minimized by reducing the thermal resistance of the current sensing resistor or 72t using a resistor with a lower tempco. Smaller sense resistance decreases power dissipation, while larger sense resistance can improve circuit accuracy by utilizing the full input range of the ACPL T.
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 7822t larger percentage of the signal amplitude. The first step in selecting a sense resistor is determining how much current the resistor will be sensing. Data subject to change.
Suitable RL value is determined from the Thermistor characteristic and the temperature range to measure. As shown in Figure 18, 0. Save to parts list Save to parts list. Add to a parts list. 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. Save to an existing parts list Save to a new parts list. However, the afpl supply current will continue to rise for differential input voltages up to approximately mV, beyond which the output supply current remains constant.
Also, multiple layers of the PC board can be used to increase current carrying capacity. Assuming a maximum input voltage of mV, the maximum value of sense resistance in this case would be about 10 m:. Hi everyone, I hope I’m posting in the right part of the forum. Note 13 4,15 The corresponding drift figures are normalized to the nominal operating conditions and show how much drift occurs as the par-ticular drift parameter is varied from its nominal value, with all other parameters held at their nominal operating values.

The effect increases as the resistor-to-ambient thermal resistance increases. The foregoing information relates to product sold on, or after, the date shown below. 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.
