SBAA652 November 2024 TMUX9832
TMUX9832 is a 32-channel low resistance single pole single throw SPST analog switch IC. TMUX9832 does not need any high voltage bias, but works on +5V supply, while still being able to support ±110V analog signals. This device is the most designed for ultrasound applications.
Since the device works at low supply voltage, TMUX9832 reduces the power consumption significantly. This is very beneficial for battery powered applications, like ultrasound smart probes. Low power consumption also leads to less heat generation. This enables fitting more devices in a smaller form factor without compromising the temperature of the probes, which otherwise can cause discomfort to the patients.
Additionally, the low bias voltage nature of the device eliminates the need to have high voltage isolation in the system to protect the user form ±100V high voltage DC supplies. This helps reducing the system size and cost.
