The TPA3245EVM is equipped with LED indicators that illuminate when the FAULT or CLIP_OTW pin (or both) goes low. See Table 6 TPA3245 115-W Stereo, 230-W Mono PurePath™ Ultra-HD Analog- Input Class-D Amplifier for more details on which events trigger the pins to go low.

The TPA3245EVM uses the OPA1678 to buffer the differential input signal to the differential inputs of the TPA3245 device. Use input RCA jack J3 to provide INA, RCA jack J14 to provide INB, RCA jack J18 to provide INC, and RCA jack J15 to provide IND with differential inputs.
12 V, 5 V, and 3.3 V. Low-dropout linear regulators (LDOs) generate supplies going to the TPA3245 device itself to reduce the chance of extra added noise. LEDs are provided on the 5-V and 3.3-V supplies for easy verification that the EVM is powered (see Figure 22).
The RESET supervisor also ensures that the device is put into reset if one of the power rails experiences a brownout. This circuit combined with the RESET switch (S1) help ensure that the TPA3245 can be placed in reset easily as needed or automatically if there is a power supply issue.
