9.2.2 Detailed Design Procedure

The TMUX113x devices can be operated without any external components except for the supply decoupling capacitors, however pull-down or pull-up resistors are recommended on the logic control inputs so that each channel is in a known state. All inputs passing through the switch must fall within the recommend operating conditions, including signal range and continuous current. For this design with a single supply of 5V the signal range can be 0V to 5V, and the maximum continuous current can be 30mA.

Industrial applications such as in factory automation and control; test and measurement benefit from using a multi-channel 2:1 switch, because it allows additional flexibility in the design.
A single 2:1 switch has numerous applications such as:

  1. Switching between an analog signal path and a calibration path so that the system is calibrated across the life of a product or after installation.
  2. Configuring a single channel to accept either a voltage or current input through software - allowing for system flexibility across applications where the end users input signals may differ.
  3. Allowing a single channel to be configured as either an analog input or analog output. Providing additional control to a system while minimizing the number of physical connectors

Figure 9-1 shows how to configure a multi-channel analog switch to address these design implementations for additional control and flexibility in the system. The on-resistance of the TMUX113x devices is very low, 2Ω typical, and has a maximum on-leakage current of 2nA which allows the devices to be used in precision measurement applications. A system with a 4mA to 20mA signal can achieve >20bits of precision due to the extremely low leakage current of the TMUX113x devices.
