APPLICATION INFORMATION
driving large capacitive loads (continued)
The unity-gain bandwidth (UGBW) frequency decreases as the capacitive load increases (see Figure 51). To
use equation (1), UGBW must be approximated from Figure 51.

driving heavy dc loads
The TLV2211 is designed to provide better sinking and sourcing output currents than earlier CMOS rail-to-rail
output devices. This device is specified to sink 500

A. This provides a greater than 90% power efficiency.
When driving heavy dc loads, such as 10 k
, the positive edge under slewing conditions can experience some
distortion. This condition can be seen in Figure 37. This condition is affected by three factors.
Where the load is referenced. When the load is referenced to either rail, this condition does not occur. The
distortion occurs only when the output signal swings through the point where the load is referenced.
Figure 38 illustrates two 10-k
load conditions. The first load condition shows the distortion seen for a 10-k
load tied to 2.5 V. The third load condition shows no distortion for a 10-k
load tied to 0 V.
Load resistance. As the load resistance increases, the distortion seen on the output decreases. Figure 38
illustrates the difference seen on the output for a 10-k
load and a 100-k
load with both tied to 2.5 V.
Input signal edge rate. Faster input edge rates for a step input result in more distortion than with slower input
edge rates.
