GENERAL DESCRIPTION

The ADT7516/ADT7517/ADT7519¹combine a 10-bit temp-

erature-to-digital converter, a 10-bit 4-channel ADC, and a

quad 12-/10-/8-bit DAC, respectively, in a 16-lead QSOP

package. The parts also include a band gap temperature sensor

and a 10-bit ADC to monitor and digitize the temperature

reading to a resolution of 0.25°C.

SMBus/I²C interface. They feature a standby mode that is

controlled through the serial interface.

The reference for the four DACs is derived either internally or

from a reference pin. The outputs of all DACs may be updated

simultaneously using the software LDAC function or the

LDAC

external

pin. The ADT7516/ADT7517/ADT7519

The ADT7516/ADT7517/ ADT7519 operate from a single 2.7 V

to 5.5 V supply. The input voltage range on the ADC channels is

0 V to 2.28 V, and the input bandwidth is dc. The reference for

the ADC channels is derived internally. The output voltage of

the DAC ranges from 0 V to V_DD, with an output voltage settling

time of 7 ms typical.

incorporate a power-on reset circuit, which ensures that the

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

write takes place.

The ADT7516/ADT7517/ADT7519’s 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.

The ADT7516/ADT7517/ADT7519 provide two serial interface

options: a 4-wire serial interface that is compatible with SPI,

QSPI, MICROWIRE, and DSP interface standards, and a 2-wire
