ADS1115IRUGT

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.
