16-bit, 860-SPS four-channel delta-sigma ADC with PGA, comparator and 1.8-V I²C bus voltage support

The

ADS1114L and ADS1115L (ADS111xL) are precision, low-power, 16-bit,

I2C-compatible, analog-to-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.
