3 Description
The ADS1113-Q1, ADS1114-Q1, and ADS1115-Q1
devices (ADS111x-Q1) are precision, low-power,
16-bit, I2C-compatible, analog-to-digital converters
(ADCs) offered in VSSOP-10 and UQFN-10
packages. The ADS111x-Q1 devices incorporate a
low-drift voltage reference and an oscillator. The
ADS1114-Q1 and ADS1115-Q1 also incorporate a
programmable gain amplifier (PGA) and a digital
comparator. These features, along with a wide
operating supply range, make the ADS111x-Q1 well
suited for power- and space-constrained, sensor
measurement applications.
The ADS111x-Q1 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-Q1 features an input multiplexer (MUX)
that allows two differential or four single-ended
input measurements. Use the digital comparator in
the ADS1114-Q1 and ADS1115-Q1 for under- and
overvoltage detection.
