... It is better to place the grounding of resistor (Rg), between input line and ground, close to INGND (Pin 12) because if OUTGND is connected to the line between Rg and INGND, THD will become worse due to current from OUTGND. Figure 1 Notes on Application Board’s Pattern Design and OUTGND is better to be made wider and CC and GND (0.1 µF) close to CC HA13150A 7 ...

... HA13150A 2. How to reduce the popping noise by Muting circuit At normal operating circuit, Muting circuit operates at high speed under 1 µs. In case popping noise becomes a problem possible to reduce the popping noise by connecting capacitor, which determines the switching time constant, between pin 10 and GND. (Following figure 2) We recommend value of capacitor greater then 1 µ ...
