TMUX1108RSVR Precision Multiplexer IC
The TMUX1108RSVR, manufactured by TI, is a single-channel, 8:1 precision analog multiplexer designed for high-performance signal routing in demanding applications. Featuring a 16-UQFN package, it operates across a wide supply voltage range of 1.08V to 5.5V, supporting both single-ended and dual-supply configurations (±2.5V). Key electrical characteristics include ultra-low on-resistance (4Ω max), minimal channel-to-channel mismatch (130mΩ), and a 90MHz bandwidth, enabling high-speed signal switching with minimal distortion. The device incorporates advanced CMOS technology, achieving sub-3pA leakage currents in both on and off states, alongside a -1pC charge injection, making it ideal for precision measurement systems. Additional features include fail-safe logic, break-before-make switching, and 2kV HBM ESD protection, ensuring robustness in industrial environments. Its operating temperature range of -40°C to 125°C further enhances reliability in extreme conditions.
