ADT7517: SPI/I2C 兼容、温度传感器、4通道ADC和4路电压输出

ADT7517 功能框图 ADT7517/ADT7517/ADT7519 在一个16引脚QSOP封装中集成了一个10位温度数字转换器、一个10位4通道ADC和一个4通道12/10/8位DAC。这些器件还内置一个带隙温度传感器和一个10位ADC，用来以0.25°C的分辨率对温度进行监控和数字化ADT7517/ADT7517/ADT7519采用2.7 V至5.5 V单电源供电。 ADC通道的输入电压范围为0 V至2.28 V，输入带宽为DC。ADC通道的基准电压从内部获得。DAC的输出电压范围为0 V至 VDD ，输出电压的建立时间典型值为7 µs。ADT7517/ADT7517/ADT7519提供两种串行接口选项：与SPI®，QSPI™， MICROWIRE™接口标准兼容的4线串行接口和双线 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，也可以从一个基准电压引脚获得。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-/ I2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 ADT7517/ADT7517/ADT7519 combine a 10-bit temperature-to-digital converter, a 10-bit 4-channel ADC, and a quad 12-/10-/8-bit DAC, respectively, in a 16-lead QSOP package. The parts also include a band gap temperature sensor and a 10-bit ADC to monitor and digitize the temperature reading to a resolution of 0.25°C.The ADT7517/ADT7517/ADT7519 operate from a single 2.7 V to 5.5 V supply. The input voltage range on the ADC channels is 0 V to 2.28 V, and the input bandwidth is dc. The reference for the ADC channels is derived internally. The output voltage of the DAC ranges from 0 V to VDD, with an output voltage settling time of 7 µs typical.The ADT7517/ADT7517/ADT7519 provide two serial interface 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 through the serial interface.The reference for the four DACs is derived either internally or from a reference pin. The outputs of all DACs can be updated simultaneously using the software LDAC function or the external LDAC pin. The ADT7517/ADT7517/ADT7519 incorporate a power-on reset circuit, ensuring that the DAC output powers up to 0 V and remains there until a valid write takes place.The wide supply voltage range, low supply current, and SPI-/ I2C-compatible interface of the ADT7517/ADT7517/ADT7519 make them ideal for a variety of applications, including personal computers, office equipment, and domestic appliances.
