MCP6L71/1R/2/4 1.3 Test Circuits
C The circuit used for most DC and AC tests is shown in F 6.8 pF Figure 1-1. This circuit can independently set VCM and VOUT; see Equation 1-1. Note that VCM is not the circuit’s common mode voltage ((V R P + VM)/2), and that G RF VOST includes VOS plus the effects (on the input offset 100 kΩ 100 kΩ error, V V V OST) of temperature, CMRR, PSRR and AOL.
