ADS1115 16-Bit ADC- 4 Channel with Programmable Gain Amplifier

The ADS1115 16-Bit ADC – 4 Channel with Programmable Gain Amplifier is commonly utilized in microcontroller projects that require precise analog-to-digital conversion. It offers 16-bit precision at a sampling rate of 860 samples per second over the I2C interface. This versatile chip can be configured to accommodate either four single-ended input channels or two differential channels.

One notable feature of the ADS1115 is its programmable gain amplifier, which can amplify smaller single-ended or differential signals by up to x16, allowing them to utilize the full measurement range. Operating within a voltage range of 2V to 5V, this ADC can handle a wide range of signals and is incredibly user-friendly.

To facilitate easy integration, the ADS1115 chip is mounted on a breakout board with ferrites to minimize noise on the AVDD and AGND lines. It communicates via the I2C protocol, and its address can be configured to one of four options, enabling the connection of up to four ADS1115 devices on a single 2-wire I2C bus, providing a total of 16 single-ended inputs.

For user convenience, example code is available for both Raspberry Pi (in the Adafruit Pi Python library) and Arduino (in the ADS1X15 Arduino library repository). Simply connect GND to ground, VDD to your logic power supply, and SCL/SDA to your microcontroller’s I2C port, then run the example code to start reading data from the ADC.
