4.9 External ADC
CYW43907 does not have any built-in ADC block. Analog measurements from the Arduino header analog pins is achieved
using an external ADC chip (MAX11615) connected to CYW43907 through an I
2
C interface (I2C_0 module-Slave Address
0x33). Table 4-10 lists the connections between CYW43907. The external ADC Circuit diagram is shown in Figure 4-7.
