GENERAL DESCRIPTION

The ADT7411¹combines 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.
