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 of the DAC ranges from 0 V to 2VREF , with an output voltage settling time of typ 7 msec. The ADT7316/17/18 provides two serial interface options, a four-wire serial interface which is compatible with SPITM, QSPITM, MICROWIRETM and DSP interface standards; and a two-wire I2C interface. It features a standby mode that is controlled via the serial interface.
