... The LM4664 features a low-power consumption shutdown mode. Shutdown may be enabled by driving the Shutdown pin to a logic low (GND). The LM4664 has fixed selectable gain of either 6dB or 12dB. The LM4664 has short circuit protection against a short from the outputs GND, or across the outputs. ...

... LM4664 and in the transducer load. The amount of power dissipation in the LM4664 is very low. This is because the ON resistance of the switches used to form the output waveforms is typically less than 0.25Ω. This leaves only the transducer load as a po- tential " ...

... For a differential gain of 12dB, the Gain Select pin should be permanently connected to GND or driven to a logic low level. The gain of the LM4664 can be switched while the amplifier is in PLAY mode driving a load with a signal without damage to the IC. The voltage on the Gain Select pin should be ...
