Frequently Asked Questions
How does TMUX1122DGKR perform at high signal frequencies and what is its bandwidth limit?
TMUX1122DGKR supports analog signal bandwidths up to 300 MHz, making it suitable for routing high-frequency signals without significant attenuation. The low on-resistance and minimal parasitic capacitance ensure that signals up to 300 MHz pass through with good fidelity in test and measurement setups.
What supply voltage does TMUX1122DGKR require and what temperature range is it rated for?
The device operates from a single 5 V supply rail and is rated across the -40°C to 125°C industrial temperature range. This broad thermal specification allows reliable switching in automotive or industrial environments where ambient temperature varies widely.
In a data acquisition design, how many independent signal channels can TMUX1122DGKR switch simultaneously?
TMUX1122DGKR provides 2 independent SPST switch channels within the 8-pin VSSOP package. Each channel switches independently, allowing simultaneous control of 2 separate analog signal paths with active-low enable signals derived from a microcontroller GPIO.
How does the active-low control logic affect board-level integration with common 3.3 V logic controllers?
The active-low enable inputs are logic-level compatible and can be driven directly from 3.3 V or 5 V GPIO outputs. Because the switch opens when the control pin is driven high and closes at logic low, designers must invert control signals from systems that expect active-high enable convention, which is easily handled by a single inverter or firmware logic.
For a portable instrument design, what package option does TMUX1122DGKR offer and how small is it?
TMUX1122DGKR comes in an 8-pin VSSOP package with a nominal body size of approximately 3 mm × 3 mm, occupying very little board area. This compact form factor is well suited for portable instruments, wearables, and space-constrained PCB designs where component density is important.
