APPLICATION INFORMATION

driving large capacitive loads (continued)

The unity-gain bandwidth (UGBW) frequency decreases as the capacitive load increases (see Figure 54). To

use equation 1, UGBW must be approximated from Figure 54.

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

When driving heavy dc loads, such as 10 k

Ω, the positive edge can experience some distortion under slewing

conditions. This condition can be seen in Figure 39. This condition is affected by three factors:

distortion occurs only when the output signal swings through the point where the load is referenced.

Figure 40 illustrates two 10-k

Ω load conditions. The first load condition shows the distortion seen for a

10-k

Ω load tied to 2.5 V. The third load condition shows no distortion for a 10-kΩ load tied to 0 V.

illustrates the difference seen on the output for a 10-k

Ω load and a 100-kΩ load with both tied to 2.5 V.
