ADT7318 - Analog Devices

ADT7318 SPI/I2C Compatible/ 10-Bit Digital Temperature Sensor and Quad Voltage Output 12/10/8-Bit DAC

The ADT7316/7317/7318 combines a 10-Bit Temperature-to-Digital Converter and a quad 12/10/8-Bit DAC respectively, in a 16-Lead QSOP package. This includes a bandgap temperature sensor and a 10-bit ADC to monitor and digitize the temperature reading to a resolution of 0.25oC. The ADT7316/17/18 operates from a single +2.7V to +5.5V supply. The output voltage .
