One application for the TMUX7236 is in data acquisition systems. For these types of input modules, accuracy and precision is key. To help account for drift over time and temperature, a calibration path is often added to calibrate the input in real time before a measurement. An SPDT switch can be used to switch in this calibration path, which the TMUX7236 is an excellent choice for. This device offers a very low on-resistance, leakage, and charge injection, which allows for a high measurement fidelity and reduces error. The break-before-make feature allows switching from the calibration path without shorting the inputs together. This device also offers on-resistance mismatch, which makes this device suitable for high precision systems. As Figure 8-1 shows, the TMUX7236 can be used in both voltage and current acquisition.
