Description

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.

Features
  • ±1A Low-side Current Sensing Solution
  • Less than 1% total unadjusted error
  • Supply: 3.3V
  • Output: 110mV to 3.19V
  • This robust circuit reference design includes theory, complete error analysis, component selection, simulation, PCB design, and measured data that correlates with the theory and simulation
