10 Power Supply Recommendations
The TMUX6121, TMUX6122, and TMUX6123 operate across a wide supply range of ±5 V to ±16.5 V (10 V to 16.5 V in single-supply mode). They also perform well with asymmetrical supplies such as VDD = 12 V and VSS= –5 V. For improved supply noise immunity, use a supply decoupling capacitor ranging from 0.1 µF to 10 µF at both the VDD and VSS pins to ground. Always ensure the ground (GND) connection is established before supplies are ramped. As a best practice, it is recommended to ramp VSS first before VDD in dual or asymmetrical supply applications.
The on-resistance of the TMUX6121, TMUX6122, and TMUX6123 varies with supply voltage, as shown in Figure 10-1
