SLOS954A July 2018 – December 2018 INA253
PRODUCTION DATA.
To demonstrate the performance of the device, the INA253, with a gain of 400mV/A, is selected for this design and powered from a 5-V supply.
Using the information in the Output Set to Mid-Supply Voltage section, the reference point is set to midscale by splitting the supply with REF1 connected to ground and REF2 connected to supply. Alternatively, the reference pins can be tied together and driven with an external precision reference.
