The HCPL-7520 isolated linear current sensing IC family is designed for current sensing in low-power electronic motor drives.The product can also be used for general analog signal isolation applications. For general applications, we recommend the HCPL-7520 (gain tolerance of ±5%). The HCPL-7520 utilizes sigma-delta (Σ−∆) analog-todigital converter technology to delivery offset and gain accuracy and stability over time and temper­a­ture. This performance is delivered in a compact, 8-pin gull-wing surface mount option 300 that meets world­wide regulatory safety standards.
