• Advanced Sigma-Delta (Σ−∆) A/D Converter Technol-

ogy

The HCPL-7800(A) isolation ampliﬁer family was designed

for current sensing in electronic motor drives. In a typical

implementation, motor currents ﬂow through an external

resistor and the resulting analog voltage drop is sensed

by the HCPL-7800(A). A diﬀerential output voltage is

created on the other side of the HCPL-7800(A) optical

isolation barrier. This diﬀerential output voltage is pro-

portional 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. Since common-

mode voltage swings of several hundred volts in tens of

nanoseconds are common in modern switching inverter

motor drives, the HCPL-7800(A) was designed to ignore

very high common-mode transient slew rates (of at least

10 kV/µs).

• Fully Diﬀerential Circuit Topology

The high CMR capability of the HCPL-7800(A) isolation

ampliﬁer provides the precision and stability needed to

accurately monitor motor current in high noise motor

control environ-ments, providing for smoother control

(less “torque ripple”) in various types of motor control

applications.

Applications

• Motor Phase and Rail Current Sensing

• Inverter Current Sensing

• Switched Mode Power Supply Signal Isolation

• General Purpose Current Sensing and Monitoring

• General Purpose Analog Signal Isolation

The product can also be used for general analog signal

isolation applications requiring high accuracy, stability,

and linearity under similarly severe noise con-ditions.

For general applications, we recommend the HCPL-7800

(gain tolerance of 3%). For precision applications Avago

Technologies oﬀers the HCPL-7800A with part-to-part

gain tolerance of 1%. The HCPL-7800(A) utilizes sigma

delta (Σ−∆) analog-to-digital converter technology,

chopper stabilized ampliﬁers, and a fully diﬀerential

circuit topology.

Together, these features deliver unequaled isolation-

mode noise rejection, as well as excellent oﬀset and

gain accuracy and stability over time and temperature.

This performance is delivered in a compact, auto-insert-

able, industry standard 8-pin DIP package that meets

worldwide regulatory safety standards. (A gull-wing

surface mount option #300 is also available).

NOTE: A 0.1 μF bypass capacitor must be connected

between pins 1 and 4 and between pins 5 and 8.

CAUTION: It is advised that normal static precautions be taken in handling and assembly

of this component to prevent damage and /or degradation which may be induced by ESD.
