3 Description

The ADS1013, ADS1014, and ADS1015 (ADS101x)

are precision, low-power, 12-bit, I

2

C-compatible,

analog-to-digital converters (ADCs) offered in a

leadless X2QFN-10, a SOT-10, and a VSSOP-10

package. The ADS101x incorporates a low-drift

voltage reference and an oscillator. The ADS1014

and ADS1015 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 perform conversions at data rates

up to 3300 samples per second (SPS). The PGA

offers input ranges from ±256mV to ±6.144V, allowing

precise large- and small-signal measurements. The

ADS1015 features an input multiplexer (MUX) that

allows two differential or four single-ended input

measurements. Use the digital comparator in the

ADS1014 and ADS1015 for under- and overvoltage

detection.
