They provide 4 +analog input pins either as single line or as differential input. + +Note: Use caution if using this sensor to control heaters. The heater min_temp +and max_temp are only verified in the host and only if the host is running and +operating normally. (ADC inputs directly connected to the micro-controller +verify min_temp and max_temp within the micro-controller and do not require a +working connection to the host.) + +``` +[ads1x1x my_ads1x1x] +chip: ADS1115 +#pga: 4.096V +# Default value is 4.096V.
