3 Description
The ADS1013, ADS1014, and ADS1015 (ADS101x)
are precision, low-power, 12-bit, I2C-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.
