* LV specs refer to low voltage analog inputs which are available on the T4 analog lines AIN4 - AIN11. HV specs refer to high voltage analog inputs which are available on analog lines AIN0 - AIN3 only.

[1] Note that these are typical input ranges. The actual minimum on the low voltage inputs might not go all the way to 0.0.

[2] Maximum voltage, compared to ground, to avoid damage to the device. Protection level is the same whether the device is powered or not.

[3] The low-voltage analog inputs essentially connect directly to a SAR ADC on the T4, presenting a capacitive load to the signal source. The high-voltage inputs connect first to a resistive level-shifter/divider. The key specification in both cases is the maximum source impedance. As long as the source impedance is not over this value, there will be no substantial errors due to impedance problems.

[4] Absolute accuracy includes INL, DNL, and all other sources of internal error at 25 C and VS=5.0V.
