ACS712 SMD 30A Current Sensor

The 30A Current Sensor ACS712 SMD delivers a proportional output voltage to the monitored current, with a low-profile footprint suitable for compact designs. Its specifications include a 66–185 mV/A sensitivity, an internal conductor resistance of 1.2 mΩ, and a factory-trimmed accuracy for stable offset and low hysteresis. The device bandwidth is configurable via the FILTER pin, supporting both AC and DC current sensing, and the output is ratio-metric to the supply voltage.

• Output: voltage proportional to current (AC or DC)
• Sensitivity: 66–185 mV/A
• Low internal resistance: 1.2 mΩ
• Factory-trimmed for accuracy with stable offset
• Minimal magnetic hysteresis
• Bandwidth selectable via FILTER pin
• Applications: automotive, sensing & instrumentation, industrial, power management, and communications

This sensor is ideal for precise current measurement in compact electronics projects and professional applications alike.
