9.3 Power Supply Recommendations

The TMUX9612 device operates across a wide supply range of ±10V to ±110V (10V to 140V in single-supply mode). It also performs well with asymmetrical supplies such as VDD = 140V and VSS= –80V or VDD = 90V and VSS= –130V. For improved supply noise immunity, use a supply decoupling capacitor ranging from 1µF to 10µF at both the VDD and VSS pins to ground. An additional 0.1µF capacitor placed closest to the supply pins will provide the best supply decoupling solution. Always ensure the ground (GND) connection is established before supplies are ramped.

VOUT is an internally generated voltage output rail. For reliable operation, connect a decoupling capacitor ranging from 0.01μF to 0.1μF between VOUT and GND on pin 10 or on the thermal pad. Having the decoupling capacitor as close to the thermal pad as possible yeilds the best performance.
