ADT7316/ADT7317/ADT7318 在一个16引脚QSOP封装中集成了一个10位温度数字转换器和一个四通道12/10/8位DAC。内置一个带隙温度传感器和一个10位ADC,能够以0.25°C的分辨率对温度进行监控和数字化。ADT7316/ ADT7317/ADT7318采用2.7 V至5.5 V单电源供电。DAC的输出电压范围为0 V至2 VREF,输出电压的建立时间典型值为7 µs。ADT7316/ ADT7317/ADT7318提供两个串行接口选项:与SPI、QSPI、MICROWIRE和DSP接口标准兼容的4线串行接口以及双线SMBus/I2C 接口。这些器件具有待机模式,可通过串行接口进行控制。 四个DAC的基准电压既可以从内部获得,也可以从两个基准电压引脚获得(每对DAC一个)。利用软件LDAC功能或外部LDAC 引脚可以同时更新所有DAC的输出。这些器件内置一个上电复位电路,确保DAC输出上电至0 V并保持该电平,直到执行一次有效的写操作为止。这些器件具有宽电源电压范围、低电源电流和SPI-/I2C兼容接口,是各种应用的理想之选,其中包括个人计算机、办公设备和家用电器。
The ADT7316/ADT7317/ADT7318*combine a 10-bit temperature-to-digital converter and a quad 12-/10-/8-bit DAC, respectively, in a 16-lead QSOP. This includes a bandgap temperature sensor and a 10-bit ADC to monitor and digitize the temperature reading to a resolution of 0.25°C. The ADT7316/ ADT7317/ADT7318 operate from a single 2.7 V to 5.5 V supply. The output voltage of the DAC ranges from 0 V to 2 VREF, with an output voltage settling time of 7 μs typically. The ADT7316/ ADT7317/ADT7318 provide two serial inter-face options, a 4-wire serial interface that is compatible with SPI, QSPI, MICROWIRE, and DSP interface standards, and a 2-wire SMBus/I²C interface. They feature a standby mode that is controlled via the serial interface.The reference for the four DACs is derived either internally or from two reference pins (one per DAC pair). The outputs of all DACs may be updated simultaneously using the software LDAC function or external LDAC pin.The ADT7316/ADT7317/ADT7318 incorporate a power-on-reset circuit that ensures the DAC output powers up to 0 V and remains there until a valid write takes place. The ADT7316/ADT7317/ADT7318 wide supply voltage range, low supply current, and SPI-/I²C-compatible interface make them ideal for a variety of applications, including personal computers, office equipment, and domestic appliances.
