#12663: 16-Bit 4-Channel ADC Module (I2C, ADS1115)

R112.00

The 16-Bit 4-Channel ADC Module, based on the ADS1115 IC, is an essential tool for microcontrollers that lack an analog-to-digital converter (ADC) or require higher precision for analog inputs. It expands the capabilities of your microcontroller by providing four additional analog input channels via the I2C interface, making it convenient and easy to use.

Key Features and Benefits:

1. High Precision: The ADC module offers 16-bit precision, providing higher resolution than the analog pins found in Arduino Uno or ESP Wemos. This ensures accurate and detailed measurements of analog signals, making it suitable for applications requiring precision measurements.

2. Programmable Gain Amplifier: The module comes with a programmable gain amplifier (PGA) that can amplify signals up to 16 times. This is beneficial when working with smaller signals that need to be boosted to the full range for accurate measurements.

3. Wide Input Range and Power Supply: The ADC module can operate on a power supply ranging from 2.0V to 5.5V, making it compatible with a wide variety of microcontroller systems. It can measure a large range of signals and works efficiently with low current consumption, which is crucial for applications with limited power resources.

4. Adjustable Data Rate: The module features a programmable data rate, allowing you to select the sampling rate from 128 to 3300 samples per second (SPS). This flexibility ensures the module can adapt to the specific requirements of your application.

5. Multiple Input Configurations: The ADC module can be configured as four single-ended input channels or two differential channels, providing versatility to accommodate various measurement scenarios.

6. Compact and User-Friendly Design: The module comes on a compact breakout board with ferrites to maintain the AVDD and AGND quiet. Its small form factor (2.55 x 0.90 cm) makes it easy to integrate into projects, and its I2C interface simplifies communication with microcontrollers.

Applications:

The 16-Bit 4-Channel ADC Module finds application in a wide range of fields, including:

1. Portable Instrumentation: Ideal for handheld devices that require precise measurements of analog signals, such as temperature sensors, pressure sensors, etc.
