Application Circuit
Cautions for mounting of IC
Note1 : For external part constant, the recommended value is described. Since the constant may differ during actual use
with the set mounted, be sure to consider optimization.
Note2 : The differential input antenna application is described. Single input with pin 1 only is also possible.
Note3 : If the spike noise between MPU and IC is large during communication, it is recommended to add limiting
resistors R1, R2, and R3 between MPU and IC.
Note4 : To reduce noise from power supply, add a capacitor between VCC_GND and between VDD_GND.
Note5 : The I2C bus communication line requires pull-up resistors R5 and R6. The commonly-employed resistance value
is 2.2k. Set the pull-up voltage to the same one of VIO of LV24230. (Supply from the same source as VIO and
VDD is recommended.
Note6 : The INT pin becomes unstable at IC startup. To protect MPU from any effects during startup, it is recommended
to add either the pull-up or pull-down resistor to set the non-active mode. (This is not necessary when the MPU
can be set to non-active by a software during initialization.
