Original question:

INA300: INA300

INA301: Is there any current sensor similar to INA301 but with enable pin?

Hello team,

Is there any current sensor  similar to INA301 but with enable pin?

INA301 spec is OK for customer, but they need an enable pin to do dynamic acquisition feature to check if the current sensor is working properly.

Based on below spec:

  • 20V common mode voltage.
  • 5~60mA signal current.
  • Integrated comparator
  • With enable pin to control input

We find INA300 is integrated comparator and enable pin, but CMRR is smaller than INA301, do you have more recommendation?

Thank you

YJ

    Hi YJ,

    We have quite a few current sense amplifiers with integrated comparators in addition to INA301. However most do not have an enable pin. INA300 is an exception that comes close to the requirements.

    The customer might be able to power INA301 with the control pin. If high speed is not a requirement, a discrete solution could be another option, made up of INA190 plus a comparator with Enable.
