The ADS1115IRUGT is a precision, low-power, 16-bit, I2C-compatible analog-to-digital converter (ADC) with the following main functions:
Signal Conversion
- High Precision123: It is a 16-bit ADC, which means it can convert analog signals into digital values with high resolution, enabling accurate measurement and representation of small changes in the input analog signal.
- Wide Input Range13: The programmable gain amplifier (PGA) provides input ranges from ±256 mV to ±6.144 V, allowing for precise measurement of both large and small signals.
Input Multiplexing
- Flexible Input Selection13: It has an input multiplexer (MUX) that allows two differential or four single-ended input measurements, providing flexibility in connecting different types of analog sources.
Data Rate and Conversion Modes
- Programmable Data Rate: The data rate is programmable from 8 samples per second (SPS) to 860 SPS, allowing the user to adjust the conversion speed according to the specific requirements of the application.
- Conversion Modes13: It can operate in either continuous-conversion mode or single-shot mode. In single-shot mode, the device is automatically powered down after one conversion, significantly reducing power consumption during idle periods.
Comparison and Detection
- Digital Comparator123: The ADS1115IRUGT incorporates a digital comparator, which can be used for under-voltage and over-voltage detection, providing a convenient way to monitor the input signal level and trigger appropriate actions when the voltage exceeds or falls below the set thresholds.
Interface and Power Management
- I2C Interface3: It uses an I2C interface with four pin-selectable addresses, making it easy to communicate with microcontrollers and other devices in an I2C bus system, simplifying the circuit design and reducing the number of pins required for connection.
- Wide Supply Range and Low Power Consumption: It has a wide supply voltage range of 2.0 V to 5.5 V and low current consumption, typically 150 µA in continuous-conversion mode, making it suitable for power- and space-constrained applications.
