SLOS954A July 2018 – December 2018 INA253
|DESIGN PARAMETER||EXAMPLE VALUE|
|Common-mode voltage||24 V|
|Maximum current||9 A|
|ADC input voltage||1.8 V|
|Supply voltage||3.3 V|
In this design, the current flow is unidirectional; therfore, the REF inputs must be tied to GND. Because of the given ADC input range and current, the 200-mV/A version is chosen.
