(1) r 2x150k gain(av) in w = for fully differential operating, the r in match is very impor- tant for cmrr, psrr and harmonic distortion performance. it s recommended to use 1% tolerance re- sistor or better. keeping the input trace as short as pos- sible to limit the noise injection. the gain is recommended to set as 2v/v or lower for apa2012 optimal performance. input capacitor, c in in the typical application, an input capacitor, c in , is required to allow the amplifier to bias the input signal to the proper dc level for optimum operation. in this case, c in and the minimum input impedance r in from a high-pass filter with the corner frequency are determined in the following equation: (2) c r 2 1 f in in ) c(highpass p = the value of c in must be considered carefully because it directly affects the low frequency performance of the circuit. for example, when r in is 100k w and the specification calls for a flat bass response are down to 40hz. the equation is reconfigured as below: (3) f r 2 1 c c in in p = when input resistance is considered, the c in is 0.2 m f. therefoe, a value in the range of 0.22 m f to 0.1.0 m f would be chosen. a further consideration for this capacitor is the leakage path from the input source through the input net- work (r in + r f , c in ) to the load. this leakage current creates a dc offset voltage at the input to the amplifier that reduces useful headroom, es- pecially in high gain applications. for this reason, a low- leakage tantalum or ceramic capacitor is the best choice. when polarized capacitors are used, the positive side of the capacitor should face the amplifier input in most appli- cations because the dc level of the amplifiers inputs are held at v dd /2. please note that it is important to confirm the capacitor polarity in the application. power supply decoupling, c s the apa2012 is a high-performance cmos audio ampli- fier that requires adequate power supply decoupling to ensure the output total harmonic distortion (thd+n) is as low as possible. power supply decoupling also pre- vents the oscillations being caused by long lead length between the amplifier and the speaker. the optimum decoupling is achieved by using two differ- ent types of capacitors that target on different types of noise on the power supply leads. for higher frequency transients, spikes, or digital hash on the line, a good low equivalent-series-resistance (esr) ceramic capacitor, typically 0.1 m f, is placed as close as possible to the de- vice vdd pin for the best operation. for filtering lower frequency noise signals, a large aluminum electrolytic capacitor of 10 m f or greater is placed near the audio power amplifier is recommended.
