Description
The ADS1013-Q1, ADS1014-Q1, and ADS1015-Q1 devices (ADS101x-Q1) are precision, low-power, 12-bit, I2C-compatible, analog-to-digital converters (ADCs) offered in a VSSOP-10 package. The ADS101x-Q1 devices incorporate a low-drift voltage reference and an oscillator. The ADS1014-Q1 and ADS1015-Q1 also incorporate a programmable gain amplifier (PGA) and a digital comparator. These features, along with a wide operating supply range, make the ADS101x-Q1 well suited for power- and space-constrained, sensor measurement applications.
The ADS101x-Q1 perform conversions at data rates up to 3300 samples per second (SPS). The PGA offers input ranges from ±256 mV to ±6.144 V, allowing precise large- and small-signal measurements. The ADS1015-Q1 features an input multiplexer (MUX) that allows two differential or four single-ended input measurements. Use the digital comparator in the ADS1014-Q1 and ADS1015-Q1 for under- and overvoltage detection.
The ADS101x-Q1 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.
