2.3 Quick Start List for Stand-Alone

Follow these steps to use the TPA2010D1 EVM stand-alone or when connecting it into existing circuits or equipment. Connections to the TPA2010D1 module header pins can be made via individual sockets, wire-wrapping, or soldering to the pins, either on the top or the bottom of the module circuit board.

-Power supply

1)Ensure that all external power sources are set to OFF.

2)Connect an external regulated power supply set to 5 V to the module VDD and GND pins, taking care to observe marked polarity.

-Inputs and outputs

3)Ensure that the signal source level is set to minimum.

4)Connect the positive lead from the audio source to the module IN+ pin and the negative lead to the IN− pin.

5)SHUTDOWN can be enabled by either depressing switch S1, or by driving the SHUTDOWN EVM pin with TTL level logic.

6)Connect a 4-Ωto 32-Ωspeaker to the module OUT+ and OUT− pins.

-Power Up

7)Verify correct voltage and input polarity and set the external power supply to ON.

The EVM begins operation.

8) Adjust the signal source level as needed.
