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 t he 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 abou t 70 degrees; gain marg in is abo ut
500 Hz and 30 kHz and transitions to –2 0 dB/de- 20 dB.
