The ADS101x devices incorporate a low-drift voltage reference and Low Current Consumption: 150 A an oscillator. The ADS1014 and ADS1015 also (Continuous-Conversion Mode) incorporate a programmable gain amplifier (PGA) and Programmable Data Rate: a digital comparator. These features, along with a 128 SPS to 3.3 kSPS wide operating supply range, make the ADS101x well Single-Cycle Settling suited for power- and space-constrained, sensor measurement applications. Internal Low-Drift Voltage Reference Internal Oscillator The ADS101x perform conversions at data rates up 2 to 3300 samples per second (SPS). The PGA offers I C Interface: Four Pin-Selectable Addresses input ranges from 256 mV to 6.144 V, allowing Four Single-Ended or Two Differential Inputs precise large- and small-signal measurements. The (ADS1015) ADS1015 features an input multiplexer (MUX) that Programmable Comparator (ADS1014 and allows two differential or four single-ended input measurements. Use the digital comparator in the ADS1015) ADS1014 and ADS1015 for under- and overvoltage Operating Temperature Range: detection. 40C to +125C The ADS101x operate in either continuous- conversion mode or single-shot mode. The devices 2 Applications are automatically powered down after one conversion Portable Instrumentation in single-shot mode therefore, power consumption is Battery Voltage and Current Monitoring significantly reduced during idle periods.
