Data sheet
ADS1114
- Ultra-small packages:
- X2QFN: 2mm × 1.5mm × 0.4mm
- SOT: 2.9mm × 2.8mm × 0.6mm
- Wide supply range: 2.0V to 5.5V
- Low current consumption: 150µA (continuous-conversion mode)
- Programmable data rate: 8SPS to 860SPS
- Single-cycle settling
- Internal low-drift voltage reference
- Internal oscillator
- I2C interface: four pin-selectable addresses
- Operating temperature range: –40°C to +125°C
- Family of devices:
- ADS1113: one single-ended (SE) or differential (DE) input
- ADS1114: one single-ended or differential input with comparator and PGA
- ADS1115: four single-ended or two differential inputs with comparator and PGA
The ADS1113, ADS1114, and ADS1115 (ADS111x) are precision, low-power, 16-bit, I2C-compatible, analog-to-digital converters (ADCs) offered in a leadless X2QFN-10, a SOT-10 package, and a VSSOP-10 package. The ADS111x devices incorporate a low-drift voltage reference and an oscillator. The ADS1114 and ADS1115 also incorporate a programmable gain amplifier (PGA) and a digital comparator. These features, along with a wide operating supply range, are useful for power- and space-constrained, sensor measurement applications.
The ADS111x devices perform conversions at data rates of up to 860 samples per second (SPS). The PGA offers input ranges from ±256mV to ±6.144V, allowing precise large- and small-signal measurements. The ADS1115 features an input multiplexer (MUX) that allows two differential or four single-ended input measurements. Use the digital comparator in the ADS1114 and ADS1115 for undervoltage and overvoltage detection.
