ADG1438 and ADG1439 switches input voltages in single-supply mode

Thread Summary

The user inquires about the operational voltage range of a switch in single-supply mode and confirms if Vss and GND can be connected together. The support engineer clarifies that the device operates safely within +5 V to +16.5 V for single supply, and suggests the ADG5408 for higher voltage needs. The user requires a higher channel count and random access, leading to a recommendation of the ADGS5414, an SPI-controlled 8 x SPST switch with a VDD up to +40V, and a request for a higher channel count switch, ideally 16 x 2, to reduce the number of ICs needed.

Based on the information from the data sheet I assume these switches can be powered in single-supply mode with Vdd up to +25V max. (Vss and GND connected together) with safe input voltages within 0V to Vdd range with any internal switches configuration. At the same time VL (logic supply) can be anywhere in the range from 2.7 V to 5.5 V. 

Please confirm these assumptions are correct.

Thanks!
