APPLICATION INFORMATION
single-supply operation (continued)
The TLV2341 works well in conjunction with digital logic; however, when powering both linear devices and digital
logic from the same power supply, the following precautions are recommended:
Power the linear devices from separate bypassed supply lines (see Figure 98); otherwise, the linear
device supply rails can fluctuate due to voltage drops caused by high switching currents in the digital
logic.
Use proper bypass techniques to reduce the probability of noise-induced errors. Single capacitive
decoupling is often adequate; however, RC decoupling may be necessary in high-frequency
applications.

input offset voltage nulling
The TLV2341 offers external input offset null control. Nulling of the input offset voltage can be achieved by
adjusting a 25-k
potentiometer connected between the offset null terminals with the wiper connected as shown
in Figure 99. The amount of nulling range varies with the bias selection. In the high-bias mode, the nulling range
allows the maximum offset voltage specified to be trimmed to zero. In low-bias and medium-bias modes, total
nulling may not be possible.
