- 1.8V logic compatibility (vs ADG708BRUZ)
Design Notes
The MUX708-Q1 can operate from a single supply (4.5V to 44V), dual supplies (±4.5V to ±22V), or asymmetric supplies. Ensure that the supply voltages are within the specified range and that the signal pins do not exceed VSS or VDD. For single-supply operation, connect VSS to GND. Proper decoupling capacitors (0.1µF and 10µF) should be placed close to the VDD and VSS pins to maintain stable operation.
For optimal performance, place the MUX708-Q1 close to the signal sources and the ADC to minimize trace length and parasitic capacitance. Use a solid ground plane under the device to reduce noise. Keep analog and digital signals separated to avoid crosstalk. The 16-TSSOP package has a thermal pad; connect it to the ground plane for improved thermal performance.
Avoid exceeding the absolute maximum ratings, particularly the supply voltage and signal pin voltages. Ensure that the address pins (A0, A1, A2) are properly driven to valid logic levels to prevent unintended channel selection. The enable pin (EN) must be high to enable the device; if not used, tie it to VDD. Also, be aware of the on-resistance variation with temperature and supply voltage, which can affect signal accuracy.
