Product Overview ADS1115 16-Bit I2C ADC ADS1113, ADS1114, and ADS1115 devices (ADS111x) are precision, low-power, 16-bit, I2Ccompatible, analog-to-digital converters (ADCs) offered in an ultra-small, leadless, X2QFN-10 package, and a VSSOP-10 package. The ADS111x devices incorporate a low-drift voltage reference and an oscillator. The ADS1114 and ADS1115 also incorporate a programmable gain amplifier (PGA) and a digital comparator. These features, along with a wide operating supply range, make the ADS111x well suited for power- and space-constrained, sensor measurement applications. The ADS111x perform conversions at data rates up to 860 samples per second (SPS). The PGA offers input ranges from ±256 mV to ±6.144 V, allowing precise large- and small-signal measurements. The ADS1115 features an input multiplexer (MUX) that allows two differential or four single-ended input measurements. Use the digital comparator in the ADS1114 and ADS1115 for under- and overvoltage detection. The ADS111x operate in either continuous conversion mode or single-shot mode. The devices are automatically powered down after one conversion in single-shot mode; therefore, power consumption is significantly reduced during idle periods Features of ADS1115 16-Bit I2C ADC Ultra-Small X2QFN Package:2 mm × 1.5 mm × 0.4 mm Wide Supply Range: 2.0 V to 5.5 V Low Current Consumption: 150 μA (Continuous-Conversion Mode) Programmable Data Rate:8 SPS to 860 SPS Single-Cycle Settling Internal Low-Drift Voltage Reference Internal Oscillator I2C Interface: Four Pin-Selectable Addresses Four Single-Ended or Two Differential Inputs (ADS1115) Programmable Comparator (ADS1114 and ADS1115) Operating Temperature Range: –40°C to 125°C Applications Portable Instrumentation Battery Voltage and Current Monitoring Temperature Measurement Systems Consumer Electronics Factory Automation and Process Control Download Datasheet for ADS1115 16-Bit I2C ADC SKU: MBR-35 Category: Interfacing Boards
