11.2.2 Detailed Design Procedure

The TMUXS1306A and TMUXS1307A can operate without any external components except for the supply decoupling capacitors. All inputs being muxed to the ADC of the MCU must fall within the recommended operating conditions of the TMUXS1306A and TMUXS1307A, including signal range and continuous current. For this design with a supply of 5V, the signal range can be 0V to 5V; the maximum continuous current can be 100mA at an ambient temperature of 85°C or 25mA at 125°C.
