Overview
The TMUX1134PWR is a precision analog switch produced by Texas Instruments. It is part of the TMUX113x family of complementary metal-oxide semiconductor (CMOS) switches. This device features four independently controlled single-pole double-throw (SPDT) switches, making it versatile for various analog and digital signal switching applications. The TMUX1134PWR operates over a wide supply voltage range, from 1.08V to 5.5V or ±2.75V in dual supply configurations, and is designed to handle bidirectional signals. Its low leakage current, low charge injection, and low on-resistance make it suitable for high precision measurement applications and portable devices.
