- 1.8 V logic-compatible control inputs for direct interfacing with low-voltage microcontrollers
- Low on-resistance (RON) minimizing signal attenuation in precision measurement paths
- Compact QFN-16 package (JESD-30 S-PQCC-N16) with RoHS e4 compliant construction
Applications
The TMUX7212RUMR is used in precision test and measurement equipment, data acquisition systems, and programmable gain amplifier stages where four independent analog channels must be switched with minimal distortion up to 48 MHz bandwidth. Its ±22 V signal handling capability allows direct switching of industrial sensor outputs and ±15 V op-amp signal chains without external voltage clamping. The 1.8 V logic compatibility enables direct control from FPGA I/O banks and low-voltage microcontrollers without level translation.

Frequently Asked Questions
What analog voltage range can the TMUX7212RUMR switch and how does it handle bipolar industrial signals?
The TMUX7212RUMR handles analog input voltages from -4.5 V to +22 V (single supply) and up to ±22 V with dual supply. This wide range accommodates ±15 V industrial sensor outputs, 4–20 mA current loop receivers, and precision op-amp signal chains without requiring external protection diodes or series resistors.
How does the 48 MHz bandwidth of the TMUX7212RUMR compare to audio and video multiplexing requirements?
With a 48 MHz -3 dB bandwidth, the TMUX7212RUMR comfortably passes video signals up to HD-SDI frequencies (27 MHz) and wideband audio measurement signals up to 20 kHz with negligible gain error. For data acquisition channels operating at sample rates above 1 Msps, the 48 MHz bandwidth ensures the settling time is well within the acquisition window for 12-bit or 16-bit ADC inputs.
Can the TMUX7212RUMR be directly controlled by a 1.8 V microcontroller or FPGA without level shifters?
Yes, the TMUX7212RUMR accepts logic high levels as low as 1.8 V on its control inputs, enabling direct connection to 1.8 V FPGA I/O banks and low-voltage microcontrollers. This eliminates the need for level-translation ICs in the control path, saving one to two additional components and 2–4 PCB vias per channel in typical layouts.
For a 4-channel DAQ board, how does the TMUX7212RUMR's QFN-16 package help with PCB density?
The QFN-16 package (S-PQCC-N16) provides all 4 SPST switch channels in a single footprint of approximately 3 mm × 3 mm, allowing a complete quad multiplexer to occupy less board area than four discrete analog switches. Exposed pad thermal construction improves heat dissipation, and 0.5 mm pitch land patterns are compatible with standard reflow assembly for high-density boards.
