ADS1115 16-Bit I2C ADC 4-Channel Programmable Gain Amplifier Module

About ADS1115 16-Bit I2C ADC 4-Channel Programmable Gain Amplifier Module

Description :

This is ADS1115 16-Bit ADC - 4 Channel with Programmable Gain Amplifier. For micro-controllers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1115 provides 16-bit precision at 860 samples - second over I2C. The chip can be configured as 4 single-end input channels or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single -differential signals to the full range. We like this ADC because it can run from 2V to 5V power - logic, can measure a large range of signals and its super easy to use. It is a great general purpose 16-bit converter.

The chips fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet. Interfacing is done via I2C. The address can be changed to one of four options so you can have up to 4 ADS1115s connect on a single 2-wire I2C bus for 16 single end inputs.

To get you start, we have example code for both the Raspberry Pi and Arduino Simply connect GND to ground, VDD to your logic power supply, and SCL-SDA to your microcontrollers I2C port and run the example code to start reading data.

Versatile 16-Bit ADC Conversion

The ADS1115 module excels in accurate analog-to-digital signal conversion across up to four channels, with a 16-bit resolution for fine data measurement. Its programmable gain amplifier allows for signal adjustment, accommodating various input ranges to match different sensor outputs, enhancing its flexibility in circuit design.


Flexible Power Compatibility

Operating between 2 and 5.5 volts, the ADS1115 supports a vast array of embedded platforms and components. This broad voltage range ensures it can be safely integrated into projects powered by standard microcontroller voltages, offering engineers more design freedom.


Seamless I2C Communication

With I2C protocol support, the ADS1115 simplifies system integration, enabling communication with a single microcontroller bus line. This streamlines wiring and supports concurrent use of multiple modules in a single system, ideal for scalable projects or prototype development.
