• Maximum input range Vss to Vdd
• Integrating converter provides good normal mode rejection
• Internal or external clock
   

The TriADC8 is a triple input integrating ADC with 8-bits of resolution. It can be configured to remove unwanted high frequencies by optimizing the integrate time. Input voltage ranges, including rail-to-rail, may be measured by configuring the proper reference voltage and analog ground. The output is configurable two’s complement or unsigned integers based on an input voltage between –Vref and +Vref centered at AGND.

Sample rates up 5000 sps are achievable, depending on the selection of the Data Clock, and CalcTime parameters. Please refer to the triADC8_SetCalcTime API for setting the CalcTime parameter.
