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

The ADS1115 16-Bit ADC – 4 Channel with Programmable Gain Amplifier is primarily utilised for microcontroller projects that require an ADC with higher precision or when an analog-to-digital converter is required. Using I2C, the ADS1115 16-Bit ADC delivers 16-bit precision at 860 samples per second. Two differential channels or four single-end input channels can be configured on the semiconductor.

A programmable gain amplifier with a maximum of x16 is also included in the ADC to assist in boosting smaller single or differential signals to their full range. We appreciate that this ADC is very user-friendly, has a wide measurement range, and operates between 2 and 5 volts for power and logic. It is an excellent 16-bit converter for common use.

Due to its small size, the ADS1115 chip is supplied on a breakout board that has ferrites to silence the AVDD and AGND. One method of interface is I2C. Up to four ADS1115s can connect to a single 2-wire I2C bus for a total of 16 single end inputs by changing the address to one of four options (see datasheet table 5).

To help you get started, we have sample code available for the Arduino (in our ADS1X15 Arduino library repository) and Raspberry Pi (in our Adafruit Pi Python library). To begin reading data, just connect SCL/SDA to the I2C port on your microcontroller, VDD to your logic power supply, and GND to ground. Then, execute the example code.
