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 an analog voltage between -24V DC to +24V DC, returning a value with 12 bit precision.

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.

The ADS1015 has four channels (labeled {{{A0}}}, {{{A1}}}, {{{A2}}} and {{{A3}}}) that can read voltages from -24V to +24V at sampling rates up to 3.3KHz with a 12-bit resolution. The Pimoroni board only provides three of these channels as usable pins.

The thumbnail image to the right is roughly the size of the Adafruit and Pimoroni boards, which measure 28 x 17mm and 24 x 21mm respectively. As of January 2020 the price of the AdaFruit board is US$9 (~NZ$14), the price of the Pimoroni board is £12 (~NZ$24). The Adafruit board is also available from DigiKey NZ at NZ$16.57.
