16 - Bit ADC Module with 4 Channels and Programmable Gain Amplifier (Purple 3pcs)

ADS1115 16-Bit ADC 4 Channel Module with Programmable Gain Amplifier (PGA)

🛠️ The ADS1115 is a highly precise 16-bit analog-to-digital converter designed to bridge the gap for microcontrollers lacking built-in ADC capabilities. This module is ideal for applications where exceptional resolution is required, delivering an impressive 860 samples per second via the I2C interface. With the capability to function as either 4 single-ended input channels or 2 differential channels, this ADC is both versatile and efficient.

🪶 One of the standout features of the ADS1115 is its programmable gain amplifier (PGA), which can amplify signals by up to a factor of x16. This is particularly beneficial for detecting and measuring smaller signals, ensuring that even minute variations can be accurately captured within the full range of the converter. Its ability to work across a broad power supply range of 2.0V to 5.5V makes it compatible with various systems, adding to its versatility as a general-purpose ADC solution.

📦 The ADS1115 board is compact and conveniently mounted on a breakout board designed to minimize signal noise. This is achieved through the inclusion of ferrite components that help maintain stable AVDD and AGND levels, ensuring high-quality readings. Communication is streamlined through the I2C interface, allowing multiple ADS1115 devices to coexist on a single bus. The address can easily be changed among four different options, accommodating up to four ADS1115s connected simultaneously for a total of 16 single-ended inputs.

🔧 Additional noteworthy features include:

• Wide Supply Range: Operates efficiently between 2.0V and 5.5V.
• Low Current Consumption: Continuous mode draws only 150μA, with an automatic shut-down feature in single-shot mode for power efficiency.
• Programmable Data Rate: Flexible data rates ranging from 8SPS to 860SPS, accommodating various application needs.
• Internal Low-Drift Voltage Reference: Enhances accuracy and stability in measurements.
• Internal Oscillator: Simplifies design requirements by eliminating the need for an external clock.
• Programmable Comparator: Adds functionality for advanced applications.

🌀 The ADS1115 module is an exceptional choice for engineers and hobbyists alike, providing a high-resolution, reliable, and easy-to-use solution for analog signal processing tasks.
