The Texas Instruments __ADS1015 +/-24V Analog Digital Converter__ is a 2 x 1.5mm integrated circuit implemented by both AdaFruit and Pimoroni as [I2C]-compatible breakout boards (Pimoroni's is a "Breakout Garden" board). It can be used to measure analog voltage sources between -24V DC to +24V DC at sampling rates up to 3.3kHz, returning a value with 12 bit precision.
