In addition to the capacitance, the withstand voltage must also be considered when selecting the capacitor. If it will be used at low temperature, the temperature characteristics must also be considered. Generally, the withstand voltage is based on the actual input and output voltage. 2 times to select the capacitor withstand voltage.<\/p>\n\n\n\n<p>The size of the input capacitor affects the frequency response of the audio. It is recommended to use a 0.1uF capacitance value for single-ended input, and a 1uF capacitance value for differential input. Single-ended input capacitance exceeding 0.1uF will cause a POP sound on the output.<\/p>\n\n\n\n<h6 class=\"wp-block-heading\">Selection of input resistance (Rin)<\/h6>\n\n\n\n<p>XA9226BB has a built-in two-stage amplifier.
