Description

The HCPL-7800A 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 high- noise motor control environ-ments, providing for smoother control (less "torque ripple") in various types of motor control applications.

This HCPL-7800A 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 generalapplications, we recommend the HCPL-7800 which exhibits a part-to-part gain tolerance of ± 5%. For precision applications, HP offers the HCPL-7800A and HCPL-7800B, each with part-to-part gain tolerances of ± 1%.

The HCPL-7800A utilizes sigma-delta (∆) analog-to-digital converter technology, chopper stabilized amplifiers, and a fully differential circuit topology fabricated using HP's 1 µm CMOS IC process. The part also couples our high-efficiency, high-speed AlGaAs LED to a high-speed, noise-shielded detector
