37 / 40 page [AK4160] MS1313-E-01 2011/11 - 37 - SYSTEM DESIGN Figure 18 and Figure 19 show the system connection diagram for the AK4160. An evaluation board [AKD4160] demonstrates the optimum layout, power supply arrangements and measurement results. <16ch Touch Switch> AK4160 CS0 ~ CS15 Touch Switch 7 8 9 x 4 5 6 / 1 2 3 + 0 = AC – VDD SCL RREF VREG IRQ2N IRQ1N RSTN IRQ0N SDA AD0 AD1 VSS 100Kohm 47nF uP Figure 18. Typical Connection Diagram for 16ch Touch Switch <8ch Touch Switch & 8ch LED Display > AK4160 CS0 ~ CS7 Touch Switch VDD SCL RREF VREG IRQ2N IRQ1N RSTN IRQ0N SDA AD0 AD1 VSS 100Kohm 47nF uP LED Display GPIO0 ~ GPIO7 VOL VOL CH CH ON MEN U MUTE EXT OFF UP UP DN DN Figure 19. Typical Connection Diagram for 8ch Touch Switch & 8ch LED Display Note: - These figures are the connection diagram when the AD0 pin = “L” and the AD1 pin = “L”. In case of the AD0 pin = “H” or the AD1 pin = “H”, their pin must be connected to VDD. - VSS of the AK4160 should be distributed separately from the ground of external controllers. - All digital input pins (SCL, SDA, AD0, AD1, RSTN pins) must not be left floating. |
