Control Inputs

Note:

The control signals applied to the EVM shutdown inputs must have sufficient current capability to overcome the 120–kΩpullup resistor on each input.

Holding down S1 places the amplifier in the shutdown state. Releasing S1 returns the amplifier to the active state.

Refer to the TPA3001D1 data sheet (SLOS398) for logic threshold voltage ratings.

8)SHUTDOWN: This pin is active low. A low on this pin shuts down the ampli- fier; a high on this pin places the amplifier in an active state. Leaving this pin floating also allows normal amplifier operation.

Power Up

9)Verify correct voltage and input polarity and set the external power supply to ON. The EVM should begin operation.

10)Adjust the signal source level as needed.
