njw1147a - 12 - application note 1. agc (auto gain control) circuit agc circuit adjusts the input signal level with boost/attenuate circuit. agc boost the low input signal level and attenuate high input signal level automatically. the agc flat levels (150mv, 300mv, 400mv and 540mv) are selectable via i 2 c bus. (refer to the following figure.) attack-recovery attack and recovery time in the attenuation processing depends on external part ca, and it in the boost processing depends on external part cb. they become longer as the capacity bigger and become shorter as it gets smaller. (recommendation value: ca=1 f, cb=4.7 f) reducing the capacity of ca may cause the distortion. as for cb, since it serves as the click noise prevention, reducing the capacity may cause the click noise upon volume changing. ir=0.5 a 9pin ca ra=4k ? cb 11pin 12pin rb=8k ? smoothing circuit of attenuate smoothing circuit of boost 0.001 0.01 0.1 1 0.001 0.01 0.1 1 agc control output voltage [vrms] input voltage [vrms] v+=9v, vin(ach+bch), f=1khz, vo(ach)output rg=600 ? , ta=25 o c 150mv 300mv 400mv 540mv agc off agc on
