GENERAL DESCRIPTION

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

ture-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.

Power-on reset to 0 V DAC output

Simultaneous update of outputs (LDAC function)

On-chip, rail-to-rail output buffer amplifier

SPI^®, I²C^®, QSPI™, MICROWIRE™, and DSP compatible

4-wire serial interface

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 μs typical.

SMBus packet error checking (PEC) compatible

16-lead QSOP package

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

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

controlled through the serial interface.

APPLICATIONS

Portable battery-powered instruments

Personal computers

Smart battery chargers

Telecommunications systems

Electronic text equipment

Domestic appliances

The reference for the four DACs is derived either internally or

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

simultaneously using the software LDAC function or the

Process control

LDAC

external

pin. The ADT7516/ADT7517/ADT7519

incorporate a power-on reset circuit, ensuring that the DAC

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

takes place.

The wide supply voltage range, low supply current, and SPI-/

I²C-compatible interface of the ADT7516/ADT7517/ADT7519

make them ideal for a variety of applications, including

personal computers, office equipment, and domestic appliances.
