The ADS1118 integrates a programmable gain amplifier (PGA), voltage reference, oscillator and high-accuracy temperature sensor. These features, along with a wide power supply range from 2 V to 5.5 V, make the ADS1118 ideally suited for power- and spaceconstrained, sensor-measurement applications. The ADS1118 can perform...
