3 Description
The ADS1114L and ADS1115L (ADS111xL) are
precision, low-power, 16-bit, I2C-compatible, analogto-
digital converters (ADCs) offered in ultra-small, 12-
pin DSBGA and a 10-pin VSSOP packages. The
ADS111xL incorporate a low-drift voltage reference
and an oscillator. The ADS111xL also incorporate
a programmable gain amplifier (PGA) and a
digital comparator. These features, along with the
device wide operating supply range, are useful for
power- and space-constrained, sensor measurement
applications.
The ADS111xL 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
ADS1115L features an input multiplexer (MUX) that
allows two differential or four single-ended input
measurements. Use the digital comparator in the
ADS111xL for under- and overvoltage detection.
