The TLV2711 is designed to provide better sinking
and sourcing output currents than previous CMOS rail-to-rail output devices. This
device is specified to sink 500 μA and source 250 μA at VDD = 3 V and
VDD = 5 V at a maximum quiescent IDD of 25 μA. These
specifications provide a greater than 90% power efficiency.
When driving heavy dc loads, such as 10 kΩ, the
positive edge under slewing conditions can experience some distortion; see also
Figure 5-23. 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 5-24 illustrates two 10-kΩ load conditions. The first load
condition shows the distortion seen for a 10-kΩ load tied to 2.5 V. The third
load condition shows no distortion for a 10-kΩ load tied to 0 V.
- Load resistance. As the load resistance
increases, the distortion seen on the output decreases. Figure 5-24 illustrates the difference seen on the output for a 10-kΩ
load and a 100-kΩ 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.
