I2C ADS1115 16 Bit ADC 4 channel Module with Programmable Gain Amplifier
Description:
I2C ADS1115 16-Bit ADC (Analog-to-Digital Converter) with a Programmable Gain Amplifier (PGA) is a high-resolution and versatile module designed to convert analog signals into digital values for processing by microcontrollers, such as Arduino or Raspberry Pi. This module is based on the ADS1115 IC from Texas Instruments and features four input channels, making it suitable for a wide range of applications that require accurate and high-precision analog-to-digital conversion.
The ADS1115 is a 16-bit ADC with a programmable gain amplifier (PGA), which allows the user to configure the gain to increase or decrease the signal range. This module operates over the I2C interface, enabling easy integration with microcontrollers, while providing excellent performance for a variety of low- to medium-speed analog measurement applications.
Features:
1. 16-Bit Resolution
2. 4 Input Channels
3. Programmable Gain Amplifier (PGA)
4. I2C Communication
5. Low Power Consumption
6. Configurable Sampling Rate
7. Internal Comparator
8. Integrated Voltage Reference
9. Simple Integration and Usage
10. Wide Input Voltage Range
11. Compact Size
