Low-side, bidirectional current-sensing circuit
CIRCUIT060007
Overview
This single-supply low-side, bidirectional current sensing solution can accurately detect load currents from –1A to 1A. The linear range of the output is from 110mV to 3.19V. Low-side current sensing keeps the common-mode voltage near ground, and is thus most useful in applications with large bus voltages.
Features
- Single 5V supply with half-supply reference
- Input: -2.22mV to 2.27mV differential
- Output: 225mV - 4.72V
- Strain gauge resistance variation: 115 - 125 Ohms
- Gain: 1001V/V
