... The IC offers five programmable gains selected using the GAIN input. The IC features a low-power shutdown mode, drawing P 1FA (typ) of supply current. Drive SHDN low to place the MAX98306 into shutdown. Drive SHDN above 1.4V for normal operation. The IC speaker amplifier features Maxim’s comprehen- sive click-and-pop suppression. During startup, the click-and-pop suppression circuitry reduces any audible transient sources internal to the device ...
