Product Summary

The HCPL7800 high CMR isolation amplifier provides a unique combination of features ideally suited for motor control circuit designers. The product provides the precision and stability needed to accurately monitor motor current in highnoise motor control environments, providing for smoother control (less torque ripple) in various types of motor control applications. This product paves the way for a smaller, lighter, easier to produce, high noise rejection, low cost solution to motor current sensing. The product can also be used for general analog signal isolation applications requiring high accuracy, stability and linearity under similarly severe noise conditions. For general applications, we recommend the HCPL7800 which exhibits a part-to-part gain tolerance of ± 5%. For precision applications, HP offers the HCPL7800A and HCPL7800B, each with part to part gain tolerances of ± 1%.
