The ADS1115 device is a 16-bit high precision low power analog-to-digital converter (ADC) in a subminiature vSSOP-10 package. The ADS1115 device uses a low drift voltage reference and oscillator. The ADS1115 also features a programmable gain amplifier (PGA) and a digital comparator. These features, combined with a wide range of working power supply voltages, make the ADS1115 ideal for EMIRR +IN OPAx189 at specific frequencies often encountered in power-constrained and space-constrained sensor measurement applications. The ADS1115 can perform conversions at data rates up to 860 samples per second (SPS). PGA offers an input range from ±256mV to ±6.144 for accurate size signal measurement. The ADS1115 has an input multiplexer (MUx) that enables two differential input measurements or four single-ended input measurements. Undervoltage and overvoltage detection can be performed using a digital comparator in the ADS1115. The ADS1115 can operate in both continuous transfer mode and single flush mode. In single-flush mode, these devices can be automatically powered off after a single conversion; Thus, the power consumption during idle periods is significantly reduced.
