The ADT7411ARQ combines a 10-bit temperature-to-digitalconverter 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 of0.25°C. The ADT7411ARQ operates from a single 2.7 V to 5.5 Vsupply. 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 forthe ADC channels is derived internally. The ADT7411ARQ providestwo serial interface options: a 4-wire serial interface compatiblewith SPI, QSPI, MICROWIRE, and DSP interface standards,and a 2-wire SMBus/I2C interface. It features a standby modethat is controlled via the serial interface.
The ADT7411’s wide supply voltage range, low supply current,and SPI-/I2C-compatible interface make it ideal for a variety of applications, including PCs, office equipment, and domesticappliances.
