History
Bjarki Arge Andreasen e0363f252d sensor: mcux_acmp: namespace driver and kconfigs 
The mcux_acmp will get support by the comparator subsystem. To avoid
namespace clashes, namespace the driver, kconfigs and use the
MCUX_ACMP config solely to select the MCUX SDK driver.

.. zephyr:code-sample:: mcux_acmp
   :name: NXP MCUX Analog Comparator (ACMP)
   :relevant-api: sensor_interface

   Get analog comparator data from an NXP MCUX Analog Comparator (ACMP).

Overview
********

This sample show how to use the NXP MCUX Analog Comparator (ACMP) driver. The
sample supports the :ref:`twr_ke18f`, :ref:`mimxrt1170_evk`, :ref:`frdm_ke17z`
, :ref:`frdm_ke17z512` and :ref:`mimxrt1180_evk`.

The input voltage for the negative input of the analog comparator is
provided by the ACMP Digital-to-Analog Converter (DAC). The input voltage for
the positive input can be adjusted by turning the on-board potentiometer for
:ref:`twr_ke18f` board, for :ref:`mimxrt1170_evk` the voltage signal is
captured on J25-13, the :ref:`frdm_ke17z` and :ref:`frdm_ke17z512` boards are
captured in J2-3, the :ref:`mimxrt1180_evk` board are captured in J45-13, need
change the external voltage signal to check the output.

The output value of the analog comparator is reported on the console.
