This single-supply low-side, bi-directional current sensing solution can accurately detect load currents from -1 A to 1 A. The linear range of the output is from 110 mV to 3.19 V. The design utilizes the OPA2313 configured as a difference amplifier and reference voltage buffer.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
