The ADT74111 combines a 10-bit temperature-to-digital converter and a 10-bit 8-channel ADC in a 16-lead QSOP. This includes 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 ADT7411 operates from a single 2.7 V to 5.5 V supply. The input voltage on the ADC channels has a range of 0 V to 2.25 V and the input bandwidth is dc. The reference for the ADC channels is derived internally. The ADT7411 provides two serial interface options： a 4-wire serial interface compatible with SPI， QSPI， MICROWIRE， and DSP interface standards， and a 2-wire SMBus/I2 C interface. It features a standby mode that is controlled via the serial interface. The ADT7411’s wide supply voltage range， low supply current， and SPI-/I2 C-compatible interface make it ideal for a variety of applications， including PCs， office equipment， and domestic appliances
