+    As per (`datasheet <http://www.ti.com/lit/ds/symlink/ads1115.pdf>`__, `Adafruit`_) Section 7.3 Note 2: 
+    "No more than VDD + 0.3V must be applied to the analog inputs of the device."
+    This means if you power the device with 3.3V, take care not to supply the 4 AIN pins with more than 3.6V.

 The ADS1115 has a multiplexer that can be configured to measure voltage between several pin configurations. These are:
 
  - ``A0_A1`` (between Pin 0 and Pin 1)
