Texas Instruments ADS1018
The ADS1018 is a precision, low-power, 12-bit, noisefree, analog-to-digital converter (ADC) that provides all features necessary to measure the most common sensor signals in an ultrasmall, leadless, X2QFN-10 or VSSOP-10 package. The ADS1018 integrates a programmable gain amplifier (PGA), voltage reference, oscillator and high-accuracy temperature sensor. These features, along with a wide powersupply range from 2 V to 5.5 V, make the ADS1018 ideally suited for power- and space-constrained, sensor-measurement applications.| Part No. | ADS1018 |

DESCRIPTION
The ADS1018 performs conversions at data rates up to 3300 samples per second (SPS). The PGA offers input ranges from ±256 mV to ±6.144 V, allowing both large and small signals to be measured with high resolution. An input multiplexer (mux) allows measurement of two differential or four single-ended inputs.
