11 Power-Supply Recommendations
The MUX50x operates across a wide supply range of ±5 V to ±18 V (10 V to 36 V in single-supply mode). The
MUX508 and MUX509 operate equally well with either dual supplies (±5 V to ±18 V), or a single supply (10 V to
36 V). They also perform well with unsymmetric supplies such as V_DD = 12 V and V_SS = –5 V. For reliable
operation, use a supply decoupling capacitor with a capacitance between 0.1 µF to 10 µF at both the VDD and
VSS pins to ground.
The on-resistance of the MUX50x varies with supply voltage, as illustrated in Figure 44.
