Operating range 3.0 V to 15 V (absolute max 18 V). Typical supply current 4 mA at 5 V. Recommend 100 nF decoupling capacitor to GND. |+| 2 | OUT | output | Ratiometric analog linear output proportional to magnetic flux density. Quiescent output = VDD/2 at B=0 (2.42-2.58 V at VDD=5 V). Sensitivity 2.5 mV/Gauss (CH604), sink capability ~1 mA, source capability ~2 mA at 5 V.
