- Wide supply range: 2.0 V to 5.5 V
- Low current consumption: 150 µA (continuous-conversion mode)
- Programmable data rate: 128 SPS to 3.3 kSPS
- Single-cycle settling
- Internal low-drift voltage reference
- Internal oscillator
- I 2C interface: Four pin-selectable addresses
- Family of devices:
- ADS1013-Q1: 1 single-ended (SE) or differential input (DE)

The ADS1013-Q1, ADS1014-Q1, and ADS1015-Q1 ( ADS101x-Q1) are precision, low-power, 12-bit, I 2C-compatible, analog-to-digital converters (ADCs) offered in VSSOP-10 and UQFN-10 packages. The ADS101x-Q1 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, are useful 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.
