bias-select feature
The TLV2342 offers a bias-select feature that allows the user to select any one of three bias levels, depending
on the level of performance desired. The tradeoffs between bias levels involve ac performance and power
dissipation (see Table 1).

bias selection
Bias selection is achieved by connecting BIAS SELECT to one of three voltage levels (see Figure 1). For
medium-bias applications, it is recommended that the bias-select pin be connected to the midpoint between the
supply rails. This procedure is simple in split-supply applications since this point is ground. In single-supply
applications, the medium-bias mode necessitates using a voltage divider as indicated in Figure 1. The use of
large-value resistors in the voltage divider reduces the current drain of the divider from the supply line. However,
large-value resistors used in conjunction with a large-value capacitor require significant time to charge up to
the supply midpoint after the supply is switched on. A voltage other than the midpoint may be used if it is within
the voltages specified in the following table.
