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.
