ACHS-712x Current Sensor Carriers
These current sensors are carrier boards or breakout boards for Broadcom’s ACHS-712x Hall effect-based linear current sensors. They operate from 4.5 V to 5.5 V and are intended for use in 5 V systems. The following list details some of the sensor’s key features:
- Analog voltage output proportional to the current (and centered around 2.5 V for the bidirectional versions).
- The conductive path internal resistance is typically 0.7 mΩ, and the PCB is made with 2-oz copper, so very little power is lost in the board.
- Use of a Hall effect sensor means the IC is able to electrically isolate the current path from the sensor’s electronics, which allows the sensor to be inserted anywhere along the current path and to be used in applications that require electrical isolation.
- 80 kHz bandwidth that can optionally be decreased by adding a capacitor across the board pins marked “filter”.
- High accuracy and reliability: typical total output error of ±1.5% at room temperature with factory calibration, an extremely stable output offset voltage, and almost zero magnetic hysteresis.
- Robust sensor IC can tolerate 100 ms transient current spikes up to 100 A.
- Wide operating temperature range of -40°C to 110°C.
