UNISONIC TECHNOLOGIES CO., LTD PA3017 CMOS IC 2W STEREO AUDIO AMPLIFIER DESCRIPTION As a stereo audio speaker which is operating on a single 5V supply, the UTC PA3017 is capable of delivering 2W of output power per channel into 3Ω loads with less than 1% THD+N. Way of two terminals (GAIN0 and GAIN1) can configured and control the amplifier gain. It also provide gain settings of 6 dB, 10 dB, 15.6 dB, and 21.6 dB (inverting). Other features include internal gain control which requires few external components, an active-low shutdown mode input and thermal shutdown protection.

When CI is required to allow the amplifier to bias the input signal to the proper dc level for optimum operation, it’s value can be calculate by this equation: CI=1/(2πRIFC) RI:Input Impedance FC:High-pass Filter’s Frequency The low leakage tantalum or ceramic capacitors are suggested to be used as the input coupling capacitors, because of the small leakage current of the input ca-pacitors will cause the dc offset voltage at the input to the amplifier that reduces the operation headroom, especially at the high gain applications. It is important to let the positive side connecting to the higher dc level of the application when using the polarized capacitors. Gain setting (VS GAIN0, GAIN1 and RI) Gain setting is determined by GAIN0 and GAIN1. The gains listed in the next table are realized by changing the taps on the input resistors inside the amplifier which will cause the internal input impedance(R I) to be dependent on the gain setting as we can see listed in the next table.
