The sensor operates at 5V and its analog voltage output has a sensitivity of 185mV/A centered at 2.5V with a typical error of ±1.5% and a 80kHz bandwidth.
Optimized bidirectional current range is from -5A to +5A, but its robustness allows survival of the device at up to 5× overcurrent conditions. Top silkscreen shows the direction that is interpreted as positive current flow.
The IC has an internal filter resistance of 1.7kΩ, and the carrier board includes a 1nF filter capacitor, which produces a low-pass RC filter with a 93,6kHz cutoff frequency.
You can improve sensing system accuracy for low-frequency sensing applictations by adding a capacitor in parallel with the integrated 1nF capacitor across the component pads labeled as CF (see notes on datasheet).
