3.1 Open Loop Gain and Phase Response

Figure 14 illustrates the open loop gain and phase cade between 30 kHz and its unity gain crossover

response of the CS3011/CS3012. The gain slope frequency at about 2.4 MHz. Phase margin at unity

of the amplifier is about –100 dB/decade between gain is about 70 degrees; gain margin is about

500 Hz and 30 kHz and transitions to –20 dB/de- 20 dB.
