Functional Description

This voltage input allows the conversion of an analog voltage into a digital value. Voltage inputs are useful for many circuits including sensors with analog outputs and measuring supply voltages.

 

Hardware Interface: The PSoC pin is a high impedance analog input connection to the Analog to Digital Converter (ADC). The input voltage is scaled through a voltage divider to the native PSoC voltage precision reference range (0-2600 mV).

 

Software Interface: 16-bit signed integer, stored most significant byte first, contains the converted voltage in whole number format to 1mV resolution (example: 2.123VDC stored as 2123).
