Product description: Sensor of the current ACHS-7123
The sensor is based on Hall effect, itis suitable to use in 5 V systems. The minimum sensor's supply voltage is 4.5 V, maximum - 5.5 V.
The main features of the system
- The system was designed for the current flowing in both directions (from -30 to 30 A), in our offer available are alsoother versions.
- A small losses of power
- low resistance of the conductive path (0,7mΩ)
- the PCB is made of copper with a thickness of 70µm
- The current paths are isolated from a current path
- The possibility to install anywhere
- Work in a wide temperature range from-40 °C to 110 °C
- Accuracy at room temperature: 1,5 %
- Bandwidth of up to 80 kHz (reduction by using the appropriate capacitor)

The connection method of the system
The sensor requires connecting of a voltage supply from 4.5 V to 5.5 V over the fields VCC and GND. The output is analog voltage proportional to measured current (66 mV/A, centered at 2.5 V).
- Input current (IP+ and IP-)
- The logical power (VCCandGND)
- Sensor's output (OUT)
The connection method of the system
- Input current: (IP+ and IP-)
- The logical power: (VCC and GND)
- Sensor's output: (OUT)
FILTER pin allows you to configure the bandwidth of the board by adding a capacitor CF to ground in parallel with a capacitor of 1 nF. Without the additional filter capacitor, the transmission bandwidth is 80 kHz. More information about the impact of the external capacitor of the filter on the bandwidth, is inthe catalogue's note.
