BROADCOM HCPL7800300E Current Sensing Amplifier
The HCPL-7800-300E is an isolation amplifier designed for precise current sensing in electronic motor drives. It measures motor current by sensing voltage drops across an external resistor, then provides a differential output voltage across an optical isolation barrier. This output is proportional to the motor current and can be converted to a single-ended signal with an operational amplifier, as shown in the recommended circuit. Engineered to withstand high common-mode transient slew rates of at least 10 kV/μs, it effectively ignores rapid voltage swings common in modern switching inverter drives. Its high common-mode rejection (15 kV/μs at 1000V VCM), low gain drift (0.00025 V/V/°C), and low non-linearity (0.004%) ensure accurate and stable current measurement in noisy environments. Featuring a fully differential topology and advanced sigma-delta analog-to-digital converter technology, it is suitable for motor drive and control, power management, sensing, and instrumentation applications. Due to high market demand, lead times may be extended, and delivery dates could fluctuate. This product is exempt from discounts.
