GENERAL DESCRIPTION

The ADT7316/ADT7317/ADT7318¹combine a 10-bit

temperature-to-digital converter and a quad 12-/10-/8-bit

DAC, respectively, 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

ADT7316/ ADT7317/ADT7318 operate from a single 2.7 V to

5.5 V supply. The output voltage of the DAC ranges from 0 V

to 2 V_REF, with an output voltage settling time of 7 μs typically.

The ADT7316/ ADT7317/ADT7318 provide two serial inter-

face 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 via the serial interface.

The reference for the four DACs is derived either internally

or from two reference pins (one per DAC pair). The outputs

of all DACs may be updated simultaneously using the software

LDAC

LDAC function or external

pin. The ADT7316/ADT7317/

ADT7318 incorporate a power-on-reset circuit that ensures the

DAC output powers up to 0 V and remains there until a valid

write takes place.

The ADT7316/ADT7317/ADT7318 wide supply voltage range,

low supply current, and SPI-/I²C-compatible interface make

them ideal for a variety of applications, including personal

computers, office equipment, and domestic appliances.
