Operating from a 5V supply and using the internal reference and buffer, each channel of this SoftSpanTM ADC can be independently configured on a conversion-by-conversion basis to accept ±4.096V, 0V to 4.096V, ±2.048V, or 0V to 2.048V signals.
Individual channels may also be disabled to increase throughput on the remaining channels.
