A Parameter Symbol Input-Output Elcodis is a trademark of Elcodis Company Ltd. R3 and R5 are selected to provide enough current to drive the bases of Q2 and Q4. Dxtasheet circuit has a bandwidth of about 1. Copy your embed code and put on your site: Assuming that A1 is a perfect op-amp, no current flows into the inputs of A1; therefore, all of the current flowing through R1 will flow through PD1.

The relationship between the input optical power and the output current of a photodiode is very linear. Precision analog isolation amplifier. Page 19 The fi nal circuit shown in Figure 19 isolates a bipolar analog signal using only one optocoupler and generates two output signals: Two example circuits that operate with bipolar input signals are discussed in the next section.


The two OP-AMPS shown are two separate LM, and not two channels in a single dual package, otherwise the loop side and output side will not be properly isolated. Contact your Avago sales representative or authorized distributor for information. IPD2 error to best fit line is the deviation below and above the best fit line, expressed as a percentage of the full scale output. Page 3 Package Outline Drawings This output current generates a voltage across R3, which is then sensed by R2.


LED input current vs.

Gull Wing Surface Mount Option Example Application Circuits The circuit shown IPD1 is equal to the current in R1 and is given by the following equation: Because the basic circuit operation has not changed, the circuit still has good gain stability. Because a photodiode can conduct current in only one direction, two diodes D1 and D2 are used to steer the input current to the appropriate terminal of input photodiode PD1 to allow bipolar input currents.

As in the simpler circuits, the input amplifier adjusts the LED current so that both of its input terminals are at the same voltage. However, an additional amplifier is used to provide an appropriate offset voltage to the other amplifiers that exactly cancels the diode voltage drops to maintain circuit accuracy.


Two topologies that allow for bipolar operation are shown in Dataxheet An analysis similar to the one above yields the following expression relating output current to input voltage: Contact your Avago sales representative or authorized distributor for information.

HCNRE datasheet and specification datasheet. This allows the designer to make perf- ormance trade-off s that would otherwise be diffi hcnr2011-000e In the high-speed circuit discussed above, the input and output circuits are stabilized by reducing the local loop gains of the input and output circuits.


External Clearance L IO1 9.

It’s a community-based project which helps to repair anything. HCNR fig 2 0. Q3 2N Vcc 5.

IMRR is defined as the ratio of the signal gain with signal applied to VIN of Figure 16 to the isolation mode gain with VIN connected to input common and the signal applied between the input and output commons at 60 Hz, expressed in dB.

And R7 is selected so that Q4 operates at about the same collector current as Q2.

The lower gains, higher input currents and higher offset voltages affect the accuracy of the circuit, but not the way it operates.

For example, when the input signal positive, optocoupler OC1 is active while OC2 is turned off. As mentioned above, only one optocoupler is used. The feedback amplifier acts to stabilize and linearize the light output of the LED.
