ADS1115IDGST

The ADS1113, ADS1114, and ADS1115 devices
(ADS111x) are precision, low-power, 16-bit, I
2Ccompatible, analog-to-digital converters (ADCs)
offered in an ultra-small, leadless, X2QFN-10
package, and a VSSOP-10 package. The ADS111x
devices incorporate a low-drift voltage reference and
an oscillator. The ADS1114 and ADS1115 also
incorporate a programmable gain amplifier (PGA) and
a digital comparator. These features, along with a
wide operating supply range, make the ADS111x well
suited for power- and space-constrained, sensor
measurement applications.
The ADS111x perform conversions at data rates up
to 860 samples per second (SPS). The PGA offers
input ranges from ±256 mV to ±6.144 V, allowing
precise large- and small-signal measurements. The
ADS1115 features an input multiplexer (MUX) that
allows two differential or four single-ended input
measurements. Use the digital comparator in the
ADS1114 and ADS1115 for under- and overvoltage
detection.
The ADS111x operate in either continuousconversion 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.
