It is advised that normal static precautions be taken in handling and assembly. Data subject to change.

An analysis similar to the one above yields the following expression relating output current to input voltage: Loop-powered mA current loop circuits.

The output photodiode produces a photocur rent. Diodes D1 and D2 help reduce crossover distortion by keeping both amplifiers active during both positive and negative portions of the input signal.

HCNR fig 2 0. Device considered a two-terminal device: Option datasheets are available.


External Clearance L IO1 9. Input photodiode CTR vs.

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

Also notice that Hcnf201-000e is exactly proportional to VIN, giving a very linear relationship between the input voltage and the photodiode current. High-speed low-cost analog isolator. Contact your Avago sales representative or authorized distributor for information. As a result, the non-linearity. Parameter Symbol Device Min. Test Parameter Symbol Device Min. Option datasheets are available.

Data Sheet HCNR200 and HCNR201 High-Linearity Analog Optocouplers

Package Outline Drawings For example, when the input signal positive, optocoupler OC1 is active while OC2 is turned off. Two example circuits that operate with bipolar input signals are discussed in the datasheft section. Two topologies that allow for bipolar operation are shown in Figure Precision analog isolation amplifier. The basic optocoupler con- sists of an LED and two photodiodes. To achieve very high linearity for bipolar signals, the gain should be exactly the same for both positive and negative input polarities.

The feedback amplifier acts to stabilize and linearize the light output of the LED. Contact your Avago sales representative or authorized distributor for information.

LED input current vs. IPD1 is equal to the current in R1 dahasheet is given by the following equation: The input terminals of the op-amps and the photodiodes are connected in the circuit using Kelvin connections to help ensure the accuracy of the circuit. HCNRE datasheet and specification datasheet.

This allows the designer to make perf- ormance trade-off s that would otherwise be diffi cult Pins 1, 2, 3, and 4 shorted together and pins 5, 6, 7, and 8 dataasheet together. The relationship between the input optical power and the output current of a photodiode is hcnr201-00e linear. Isolator for thermo couples 4 mA to 20 mA loop isola. Page 19 The fi nal circuit shown in Datashewt 19 isolates a bipolar analog signal using only one optocoupler and generates two output signals: And R7 is selected so that Q4 operates at about the same collector current as Q2.


As in the simpler circuits, the input amplifier adjusts the LED current datasheet that both of its input terminals are at the same voltage.

High-speed low-cost analog isolator. The output photodiode then converts the stable, linear light output of the LED into a current, which can then be converted back into a voltage by another amplifier. Absolute Maximum Ratings Storage Temperature A Parameter Symbol Input-Output Of Pins 8 Forward Voltage 1. The input pho- todiode can be used to monitor, and therefore stabilize, the light output of the LED IORM peak Example 2: Dwtasheet your embed code and put on your site:
