Overview

The ADS1115IDGSR is a precision, 16-bit analog-to-digital converter (ADC) featuring four single-ended or two differential input channels. It integrates a low-drift voltage reference, an oscillator, and a programmable gain amplifier (PGA) to simplify the measurement of small-signal sensors.

Why Choose This Part

The device offers a wide supply range from 2V to 5.5V and consumes only 150uA during operation, making it ideal for battery-powered applications. Its I2C interface supports four programmable addresses, allowing multiple ADCs to share a single bus while providing integrated comparator functions for threshold monitoring.

Applications

Battery Voltage Monitoring
Utilizing the high-resolution 16-bit architecture and internal reference to precisely monitor individual cell voltages in portable electronics.
Process Control Systems
Interfacing with industrial 4-20mA loops or voltage-output sensors where high precision and noise rejection are required.
Temperature Measurement
Connecting directly to thermocouples or RTDs using the integrated PGA to amplify low-voltage signals without external circuitry.
