ADS1015 ADC - how can it measure 24v?

Hi

I have a simple question - just purchased your

This ADS1015 ADC (analog-to-digital converter) breakout has three channels that can read voltages from -24V to +24V at sampling rates up to 3.3KHz with 12-bit resolution.

However reading the technical details I cant see how it achieves a reading outside of gnd - vcc +/-300mv. I want to use the unit to track voltage on a 3-cell LIPO, and am hoping it can do this readily without needing to put in resistors to divide down.

If it cannot do this, why is it advertised as +/-24v?

Thanks!
