TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information The OPAx191 family offers outstanding dc precision and ac performance. These devices operate up to 36-V supply rails and offer true rail-to-rail input/output, ultralow offset voltage and offset voltage drift, as well as 2-MHz bandwidth and high capacitive load drive. These features make the OPAx191 a robust, high-performance operational amplifier for high-voltage industrial applications. 9.2 Typical Applications 9.2.1 Low-side Current Measurement Figure 61 shows the OPA191 configured in a low-side current sensing application. For a full analysis of the circuit shown in Figure 61 including theory, calculations, simulations, and measured data, see TI Precision Design TIPD129, 0-A to 1-A Single-Supply Low-Side Current-Sensing Solution . Figure 61. OPA191 in a Low-Side, Current-Sensing Application 9.2.1.1 Design Requirements The design requirements for this design are: • Load current: 0 A to 1 A • Output voltage: 4.9 V • Maximum shunt voltage: 100 mV |
