ADT7411 SPI®-/I2C®-Compatible, 10-Bit Digital Temperature Sensor and 8-Channel A/D Converter

Applications Portable battery-powered instruments PCs Smart battery chargers Telecommunications systems electronic test equipment Domestic appliances Process controls

The ADT7411 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/I2C 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-/I2C-compatible interface make it ideal for a variety of applications, including PCs, office equipment, and domestic appliances.
