3 Description
The ADS1014L and ADS1015L (ADS101xL) are
precision, low-power, 12-bit, I2C-compatible, analogto-
digital converters (ADCs) offered in ultra-small,
12-pin DSBGA and a 10-pin VSSOP packages.
The ADS101xL incorporate a low-drift voltage
reference and an oscillator. The ADS101xL 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 ADS101xL 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
ADS1015L features an input multiplexer (MUX) that
allows two differential or four single-ended input
measurements. Use the digital comparator in the
ADS101xL for under- and overvoltage detection.
