Offset Voltage Calculations CALCULATING TOTAL OUTPUT OFFSET ERROR DUE TO IB AND VOS The equations shown in Figure 1 below are useful in referring all the offset voltage and induced offset voltage from bias current errors to the either the input (RTI) or the output (RTO) of the op amp. The...
The noise gain for a typical second-order system is repeated in Figure 3 below. It is quite easy to perform the voltage noise integration in two steps, but notice that because of peaking, the majority of the output noise due to the input voltage noise will be determined by the high ...

For a reference on noise calculations, refer to the Band-Pass KRC or Sallen-Key Filter section. GAIN LINEARITY Gain linearity reduces errors in closed-loop configurations. The straighter the gain curve, the lower the maximum error over the input signal range. This is especially true for ...
The protection works by monitoring the temperature of the device and turning off the op amp output drive for temperatures above 170°C. Figure 7-4 shows an application example for the OPA990 that has significant self heating because of its power dissipation (0.81 W). Thermal calculations ...
Figure 1, Equation 1, Equation 2 and Equation 3 can be written by inspection if it is assumed that there are no loading concerns between the blocks. The no loading assumption is implicit in all block dia- gram calculations, and this requires that the output imped- ance of a block be ...
The analog engineer’s calculator is designed to speed up many of the repetitive calculations that analog circuit design engineers use on a regular basis. This PC-based tool provides a graphical interface with a list of various common calculations ranging from setting operational-amplifier (...)Abo...
