Texas Instruments TMUX4827 SPDT 2-Channel Switch
Texas Instruments TMUX4827 SPDT 2-Channel Switch is a complementary metal-oxide semiconductor (CMOS) multiplexer with two selectable 2:1, single-pole, double-throw (SPDT) switch channels. This device works with a single supply (1.8V to 5.5V) but can pass bidirectional analog and digital signals beyond the supply from -12V to 12V.
The TMUX4827 also features bidirectional powered-off protection up to ±12V, isolating the switch even when there is no supply voltage (VDD = 0V). Without this protection feature, any voltage on the switch can back-power the supply rail through an internal ESD diode and cause potential damage to the rest of the system.
With 0.001% THD+N and 1mΩ RON-flatness, the Texas Instruments TMUX4827 is well suited for passing precision analog and audio signals without adding distortion.
