The AD7818ARMZ is a 1-channel 10-bit Analog-to-digital Converter (ADC) with on-chip temperature sensor that can operate from a single 2.7 to 5.5V power supply. The device contains a 9μs successive approximation converter based around a capacitor digital-to-analog converter (DAC), an on-chip temperature sensor with an accuracy of ±2°C, an on-chip clock oscillator, inherent track-and-hold functionality and an on-chip reference. The on-chip temperature sensor of the converter can be accessed via channel 0. When channel 0 is selected and a conversion is initiated, the resulting ADC code at the end of the conversion gives a measurement of the ambient temperature with a resolution of ±0.25°C. It has a flexible serial interface that allows easy interfacing to most microcontrollers.
