8 Application and Implementation

Note

Information in the following applications sections is not part of the TI component specification,

and TI does not warrant its accuracy or completeness. TI’s customers are responsible for

determining suitability of components for their purposes, as well as validating and testing their design

implementation to confirm system functionality.

8.1 Application Information

The TLV915x family offers excellent DC precision and DC performance. These devices operate up to 16-V

supply rails and offer true rail-to-rail input/output, low offset voltage and offset voltage drift, as well as 4.5-MHz

bandwidth and high output drive. These features make the TLV915x a robust, high-performance operational

amplifier for high-voltage industrial applications.

8.2 Typical Applications

8.2.1 Low-Side Current Measurement

Figure 8-1 shows the TLV9151 configured in a low-side current sensing application. For a full analysis of the

circuit shown in Figure 8-1 including theory, calculations, simulations, and measured data, see TI Precision

Design TIPD129, 0-A to 1-A Single-Supply Low-Side Current-Sensing Solution.
