Overview
The TMUX6211PWR, produced by Texas Instruments, is a complementary metal-oxide semiconductor (CMOS) analog switch. This device is part of the precision switches and multiplexers family and is designed to handle a wide range of analog and digital signals. It features four independently selectable 1:1, single-pole, single-throw (SPST) switch channels, making it versatile for various applications. The TMUX6211PWR operates with single or dual supply voltages, ranging from 4.5V to 36V and ±4.5V to ±18V, respectively, and supports asymmetric supplies. This device is known for its low on-resistance, high current support, and rail-to-rail operation, making it suitable for high precision measurement applications.
