20 / 31 page To set the gain of the difference amplifier, the common-mode range and output swing of the OPA388-Q1 must be considered. Equation 3 and Equation 4 depict the typical common-mode range and maximum output swing, respectively, of the OPA388-Q1 given a 3.3-V supply. –100 mV < VCM < 3.4 V (3) 100 mV < VOUT < 3.2 V (4) The gain of the difference amplifier can now be calculated as shown in Equation 5. Gain = Diff_Amp V V = 15.5 V V R (I I ) OUT_Max OUT_Min SHUNT MAX MIN - - ´ 3.2 V 100 mV 100 m - W ´ - - [1 A ( 1A)] = (5) The resistor value selected for R1 and R3 was 1 kΩ. 15.4 kΩ was selected for R2 and R4 because this number is the nearest standard value. Therefore, the ideal gain of the difference amplifier is 15.4 V/V. The gain error of the circuit primarily depends on R1 through R4. As a result of this dependence, 0.1% resistors were selected. This configuration reduces the likelihood that the design requires a two-point calibration. A simple one-point calibration, if desired, removes the offset errors introduced by the 0.5% resistors. 8.2.3 Application Curve 1.65 -1.0 -0.5 0 0.5 1.0 0 3.30 Input Current (A) Figure 8-2.
