10.1.4 Transducer Connection to the USS Module
Figure 10-6 shows a typical connection of two transducers to the USS output and input pins. TI recommends 1% error tolerance for the external termination resistors (Rterm0 and Rterm1) and the AC coupling capacitors (Cac0 and Cac1). Typical value of the termination resistors is in the range of 150 to 400 Ω, the AC coupling capacitors are 1 to 2 nF. Actual values should be determined to meet the requirements of each application.
