Typical Applications
AMC0380D is suitable for 6 applications: AC Voltage Sensing in Motor Drives, Grid-Tied Inverter Monitoring, Power Monitoring in Industrial Systems, Electric Vehicle Charging Stations, Uninterruptible Power Supplies (UPS), Smart Grid and Distribution Automation.
AC Voltage Sensing in Motor Drives
The AMC0380D's ±400V input range and high impedance (8.3MΩ) allow direct connection to motor phase voltages without external scaling resistors. Its reinforced isolation protects the low-voltage control circuitry from high-voltage transients, while the fixed-gain differential output interfaces directly with ADCs for accurate voltage monitoring. This simplifies the analog front-end and improves reliability in industrial motor drives.
Recommended
Grid-Tied Inverter Monitoring
In grid-tied inverters, the AMC0380D senses AC line voltages directly, thanks to its high-voltage input capability and integrated divider. The reinforced isolation meets safety requirements for grid connections, and the differential output provides noise immunity for accurate power measurement. The wide supply range (3.0V-5.5V) allows easy integration with digital controllers.
Recommended
Power Monitoring in Industrial Systems
The AMC0380D enables precise AC voltage measurement in industrial power monitoring systems. Its high input impedance minimizes loading on the measured circuit, and the integrated divider eliminates external components, reducing BOM cost and board space. The device's -40°C to 125°C operating range ensures reliable performance in harsh environments.
Recommended
Electric Vehicle Charging Stations
For EV charging stations, the AMC0380D provides isolated AC voltage sensing for metering and safety. Its reinforced isolation is crucial for user safety, and the high input range accommodates various grid voltages. The compact SSOP package fits space-constrained designs, while the differential output simplifies ADC interfacing.
Recommended
Uninterruptible Power Supplies (UPS)
In UPS systems, the AMC0380D monitors AC input and output voltages to ensure proper power quality. Its high input voltage range and isolation protect the control electronics from surges. The fixed-gain output simplifies calibration, and the wide temperature range supports continuous operation.
Recommended
Smart Grid and Distribution Automation
The AMC0380D is well-suited for smart grid applications where accurate voltage sensing is essential. Its reinforced isolation meets stringent safety standards, and the high input impedance ensures minimal impact on the grid. The device's differential output provides good common-mode rejection, enhancing measurement accuracy in noisy substation environments.

Design Notes
Maintain proper creepage and clearance distances for reinforced isolation. The 15-pin SSOP package has a specified creepage; ensure PCB layout meets the required isolation distances per safety standards. Use appropriate solder mask and keep high-voltage traces away from low-voltage side.
Place the AMC0380D close to the voltage sensing point to minimize parasitic inductance and noise pickup. Use a solid ground plane on the low-voltage side and separate high-voltage and low-voltage grounds. Route differential output traces as a pair to maintain common-mode rejection.
Do not exceed the absolute maximum input voltage ratings. The integrated divider is designed for ±400V linear range; applying higher voltages may damage the device. Also, ensure both supply rails (VDD1 and VDD2) are within 3.0V-5.5V and properly decoupled with 0.1µF capacitors.
Compliance Information
RoHS compliant per TI product page. AEC-Q100 qualified for AMC0380D-Q1 variant only.
