  • RE: INA240: conversion of differential inputs to single ended with appropriate offset

    Resolved
    The INA170 allows this. But it would be cheaper to use a plain difference amplifier like the INA500 or INA132. (All of them have a single reference input.)

  • INA170: INA170 - power sequencing

    TI Thinks Resolved
    Part Number: INA170 Hi, i want to use the INA170 to sense current in a 24V power supply. The INA170 is supplied with 3.3V on V+. The 3.3V will start a few 10ms after the 24V is applied. According to the datasheet, Vin+ and Vin- may be +40V, but only…

  • INA170 Current Direction Problem

    Other Parts Discussed in Thread: INA170 Hello, I've got an INA170 used to measure bi-directional current flow to and from a 12V battery. The battery is either charging from a PV panel or driving an LED load, never at the same time. When charging the battery…
