Overview
The TMUX1102DBVR is a single-channel analog switch IC from Texas Instruments, configured as one SPST switch. It operates on a single supply voltage ranging from 1.08 V to 5.5 V and features an extremely low on-state leakage current of 3 pA. The device exhibits a maximum on-resistance of 4.9 Ohms and draws a maximum supply current of 1 uA. Designed for surface-mount applications, it is housed in a compact SOT-23-5 package. The component supports an extended industrial temperature range, functioning reliably between -40°C and +125°C.
Feature Summary
- Ultra-low on-state leakage current of 3 pA ensures minimal signal degradation in high-impedance circuits
- Low on-resistance of 4.9 Ohms maximizes signal integrity across the passband
- Operates with a wide single-supply voltage range from 1.08 V to 5.5 V for flexible power integration
- Extended temperature rating supports operation in harsh environments up to +125°C
Applications
- Battery-powered portable instrumentation requiring minimal quiescent current
- Signal routing in data acquisition systems with high input impedance sensors
- Medical equipment where low leakage prevents measurement errors
- Automotive sensor interfaces operating under extreme temperature conditions
Procurement Notes
Verify the specific ordering suffix DBVR confirms the SOT-23-5 package and tape-and-reel shipping format. Confirm RoHS compliance status through official manufacturer documentation prior to finalizing procurement orders. Ensure the supplier provides valid traceability for the Texas Instruments manufacturing origin.
Selection Notes
Select this component when a single SPST configuration with ultra-low leakage is required. Compare against the TMUX1102DCKR if a smaller SC70-5 footprint is preferred. Evaluate the TMUX1101DCKR if alternative pinout compatibility is necessary for existing PCB layouts while maintaining similar electrical characteristics.
Part Context
This part belongs to the TMUX1102 family of low-leakage analog switches. It shares core electrical specifications with variants like the TMUX1101 series but differs in physical packaging. The DBVR suffix specifically denotes the SOT-23-5 surface-mount package optimized for space-constrained designs.
Replacement Considerations
The TMUX1102DCKR serves as a direct functional substitute with identical electrical parameters but utilizes an SC70-5 package. Verify pin-to-pin compatibility before substitution. Other TMUX110x series devices may require schematic review due to potential pinout differences.
