General Description

The Sequencing SAR ADC component gives you the ability to configure and use the different operational modes of the SAR ADC on PSoC 4. You have schematic- and firmware-level support for seamless use of the Sequencing SAR ADC in PSoC Creator designs and projects. You also have the ability to configure up to sixteen analog channels (depending on the device) that are automatically scanned with the results placed in individual result registers. An optional “Injection channel” may also be enabled by firmware to occasionally scan a signal that does not need to be scanned at the same rate as other channels.
