The following schematic and formula can be used to calculate the output offset voltage: VOO + VIO 1 ) RF RG " IIB) RS 1 ) RF RG " IIB– RF + − VI + RG RS RF IIB− VO IIB+ Figure 25. Output Offset Voltage Model general configurations When receiving low-level signals, limiting the bandwidth of the incoming signals into the system is often required. The simplest way to accomplish this is to place an RC filter at the noninverting terminal of the amplifier (see Figure 26).

The Sallen-Key filter can be used for this task. For best results, the amplifier should have a bandwidth that is 8 to 10 times the filter frequency bandwidth. Failure to do this can result in phase shift of the amplifier.
