5 / 10 page 399 Audio ICs BA5415A / BA5416 FOperation notes (1) Input circuit The structure of the input circuit is shown in Fig. 4. The IC can be used without coupling capacitors, but a maxi- mum of 0.5 µA of bias current (IBIN) flows from the input pin, so if potentiometer sliding noise results from this, connect an input capacitor CIN as shown below. To prevent degradation of the IC characteristics, the input bias resistor is not built into the IC. Connect an input bias resistor (RIN) between the input and GND (the recom- mended value is about 33k Ω). (2) Gain adjustment The gain is given by the following formula. It is possible to reduce the gain by increasing RF, but the amount of feedback will increase, and oscillation will be more likely to occur. We recommend that you set the gain to 30dB or higher. (3) Oscillation countermeasures We recommend that the capacitor (C1) connected be- tween the B. S pin and the VCC pin for oscillation preven- tion be a metal-film component with good temperature and high-frequency characteristics. Ceramic capacitors have poor temperature characteris- tics, so if used, allow sufficient oscillation margin. It is also possible to connect a capacitor for oscillation pre- vention between the output and GND (C2). The oscillation margin depends on the PCB pattern and the mounting position of the capacitor. Design your PCB after referring to the application example PCB. (4) VCC and GND lines The Pre. GND and Pow. GND are joined at pin 12, so there is a chance of crosstalk or degraded distortion per- formance due to common ground impedance in the PCB pattern. In addition, the power supply capacitor con- nected between VCC and GND is influenced by the PCB pattern, and common VCC and GND impedance may de- grade the ripple rejection and distortion. Design the PCB after referring to the application example PCB (the rec- ommended value for the power supply capacitor is 1000 µF of greater). GV = 20log RNF )RF RF |
