APPLICATION INFORMATION
driving large capacitive loads
The TLV2211 is designed to drive larger capacitive loads than most CMOS operational amplifiers. Figure 49
and Figure 50 illustrate its ability to drive loads up to 600 pF while maintaining good gain and phase margins
(R
null
= 0).
A smaller series resistor (R
null
) at the output of the device (see Figure 52) improves the gain and phase margins
when driving large capacitive loads. Figure 49 and Figure 50 show the effects of adding series resistances of
500
and 1000
. The addition of this series resistor has two effects: the first is that it adds a zero to the transfer
function and the second is that it reduces the frequency of the pole associated with the output load in the transfer
function.
The zero introduced to the transfer function is equal to the series resistance times the load capacitance. To
calculate the improvement in phase margin, equation (1) can be used.
