The ADS1015IRUGR is a low-power, 16-bit analog-to-digital converter (ADC) from Texas Instruments, designed for precision measurement in battery-operated and embedded systems. This device features four differential input channels or single-ended operation, enabling flexible connectivity to sensors and transducers. It supports a ±4.096V input range with a resolution of 16 bits, delivering high accuracy for low-level signals. The ADC operates via an I2C interface and consumes minimal power (15 µA in active mode, 0.1 µA in shutdown), making it ideal for energy-constrained applications. It is housed in a compact 8-pin VSSOP package, facilitating integration into space-limited designs.

Key Features

The ADS1015IRUGR offers programmable data rates from 8 SPS (samples per second) to 1280 SPS, balancing speed and power efficiency. Its 16-bit resolution ensures precision down to 0.125 mV (for ±4.096V range), while a 12-bit mode reduces power consumption further. The device includes a built-in programmable gain amplifier (PGA) with up to ×8 gain, extending measurement sensitivity to ±0.256V. It operates over a wide supply voltage range (2.0V to 3.6V), ensuring compatibility with single-cell Li-ion or alkaline batteries. Integrated overvoltage protection and EMI/ESD resilience enhance reliability in noisy environments.

Applications

Primarily used in industrial IoT and sensor networks, the ADS1015IRUGR is critical for monitoring strain gauges, temperature sensors, and battery voltages in wearable devices and environmental systems. It is widely employed in medical instrumentation, portable test equipment, and smart home devices requiring precise analog measurements. Its low power consumption and small footprint make it ideal for battery-powered sensors in agriculture, structural health monitoring, and consumer electronics.

Summary
