Introduction

AI Translation

The HCPL-7840 isolation amplifier is designed for current sensing in electronic motor drives. In a typical implementation, motor current flows through an external resistor, and the resulting analog voltage drop is sensed by the HCPL-7840. A differential output voltage is produced on the other side of the HCPL-7840 optical isolation barrier. This differential output voltage is proportional to the motor current and can be converted to a single-ended signal 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-7840 is designed to reject very high common-mode transient slew rates (at least 10kV/μs).

The high CMR capability of the HCPL-7840 isolation amplifier provides the accuracy and stability needed to accurately monitor motor current in high-noise motor control environments, enabling smoother control (less torque ripple) across various types of motor control applications.

The device is also suitable for general analog signal isolation applications requiring high accuracy, stability, and linearity under similarly severe noise conditions. For general applications, the HCPL-7840 (gain error of ±5%) is recommended. The HCPL-7840 is manufactured using sigma-delta (∑-Δ) ADC technology, a chopper-stabilized amplifier, and a fully differential circuit topology built on a CMOS IC process. Together, these features provide unmatched isolation-mode noise rejection, along with excellent offset and gain accuracy and stability over time and temperature. This performance is offered in a compact, auto-insertable, industry-standard 8-pin DIP package, with an SMD8 surface-mount option also available.
