Product Summary
The AD7817ARZ is a 10-bit, single- and 4-channel A/D converter with on-chip temperature sensor that can operate from a single 2.7V to 5.5 V power supply. Each part contains a 9 μs successive-approximation converter based around a capacitor DAC, an on-chip temperature sensor with an accuracy of ±2℃, an on-chip clock oscillator, inherent track-andhold functionality and an on-chip reference (2.5 V). The AD7817ARZ is a temperature monitoring only device in a SOIC/MSOP package. The applications of the AD7817ARZ include Data Acquisition Systems with Ambient Temperature, Monitoring, Industrial Process Control, Automotive, Battery Charging Applications.
