SBAS563E December 2011 – December 2022 ADS1113-Q1 , ADS1114-Q1 , ADS1115-Q1
PRODUCTION DATA
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.
