... Typical Operating Characteristics for details of the possible capacitor sizes. There is a low DC voltage on the amplifier outputs due to amplifier off- set. However, the offsets of the MAX9724C/MAX9724D are typically 1.5mV, which, when combined with a 32Ω load, results in less than 47µ current flow to the headphones ...

... Figure 2. RF Susceptibility of the MAX9724 and a Typical Headphone Amplifier 10 ______________________________________________________________________________________ Typically, the output of the device driving the MAX9724C/MAX9724D has a DC bias of half the supply voltage. At startup, the input-coupling capacitor, C charged to the preamplifier’s DC bias voltage through the MAX9724C/MAX9724D input resistor, R series 15kΩ resistor. This DC shift across the capacitor results in an audible click-and-pop ...

... Having the ability to derive 2V even 3.3V supply, can often simplify power-supply design in some systems. When the MAX9724C is used as a line driver to provide outputs that feed stereo equipment (receivers, STBs, notebooks, and desktops) with a digital-to-analog con- verter (DAC) used as an audio input source often ...

... Amplifier with 1.8V Compatible Shutdown To suppress this noise, and to provide a 2V dard audio output level from a single 5V supply, the MAX9724C can be configured as a line driver and active lowpass filter. Figure 5 shows the MAX9724C connected as 2-pole Rauch/multiple feedback filter with a passband gain of 6dB and a -3dB (below passband) cutoff frequency of approximately 27kHz (see Figure 6 for the Gain vs ...
