16.2.2.3 Application Curve

The linear response of the TMUX48xx reduces any impact to signal distortion and loss, making it an excellent choice for high precision industrial systems. The TMUX48xx utilizes a specialized architecture to keep the on-resistance extremely flat, while supporting signals beyond the supply from -15V to 15V. Additionally, the TMUX48xx supports a wide frequency range to drive output capacitive transducers. This with the low on-resistance results in an extremely low insertion loss as well.
