| Description | The ACS722LLCTR-20AB-T is a high-accuracy Hall-effect based open-loop current sensor IC designed for AC and DC current measurement up to ±20A. It operates with a supply voltage range of 3.0V to 3.6V (typically 3.3V) and provides a ratiometric analog voltage output with sensitivity of approximately 66 mV/A . The device offers bandwidth up to 80 kHz and fast response time around 5 µs, enabling real-time current monitoring . It features high linearity (±1%) and overall accuracy around ±3%, with very low offset error (~±15 mV) and low noise characteristics . The sensor supports bidirectional current sensing with galvanic isolation between primary current path and signal pins, enhancing safety and noise immunity. Typical supply current is up to 12 mA, and operating temperature range extends from -40°C to +150°C . Packaged in SOIC-8, it is suitable for motor control, power supplies, overcurrent protection, battery monitoring, and industrial current sensing applications. |
