Refer to the setting to the cereal map. The magnification can be set from ten by 200. No.A1787-11/12 LV8415CB Note in design • Stand-by function IC becomes a stand-by state at ST = “L”, and IC enters the state of operation at ST =”H”. Moreover, the register in IC is reset as for ST = “L” at times. • Hall bias The constant current output is built into for the hall element drive. The constant current value is set from detection resistance (RHG) connected from the HBIN pin impression voltage and the HGND pin between GND. Constant current value (IO) = HBIN voltage ÷ Detection resistance VCC HBIN + - HB IO H HGND Constant current value (IO) becomes about 1mA when assuming HBIN pin impressed voltage =1.0V and detection resistance = 1 kΩ from the above-mentioned calculation type. Moreover, the HGND pin must connect with the HB pin, and connect the detection resistance of a large value as much as possible when you do not use the hall bias circuit. • Operation amplifier Impress the bias to the VIN+ pin, and compose the buffer by the connection to the VOUT pin in the VIN- pin in the operational amplifier not used.
