PRELIMINARY TECHNICAL DATA

SPI/I²C^RCompatible, 10-Bit Digital Temperature

Preliminary Technical Data

Sensor and Quad Voltage Output 12/10/8-Bit DAC

ADT7316/7317/7318

FEATURES

GENERAL DESCRIPTION

ADT7316 - Four 12-Bit DACs

ADT7317 - Four 10-Bit DACs

ADT7318 - Four 8-Bit DACs

Buffered Voltage Output

The ADT7316/7317/7318 combines a 10-Bit Tempera-

ture-to-Digital Converter and a quad 12/10/8-Bit DAC

respectively, in a 16-Lead QSOP package. This includes a

bandgap temperature sensor and a 10-bit ADC to monitor

and digitize the temperature reading to a resolution of

0.25 ^oC. The ADT7316/17/18 operates from a single

+2.7 V to + 5.5 V supply. The output voltage of the DAC

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

time of typ 7 msec. The ADT7316/17/18 provides two

serial interface options, a four-wire serial interface which

is compatible with SPI^TM, QSPI^TM, MICROWIRE^TMand

DSP interface standards; and a two-wire I²C interface. It

features a standby mode that is controlled via the serial

interface.

Guaranteed Monotonic By Design Over All Codes

10-Bit Temperature to Digital Converter

Temperature range:

-40^oC to +125^oC

Temperature Sensor Accuracy of 2^oC

Supply Range : + 2.7 V to + 5.5 V

DAC Output Range: 0 - V_REF

Power-Down Current 1µA

Internal 2.25 V_RefOption

Double-BufferedInputLogic

Buffered / Unbuffered Reference Input Option

Power-on Reset to Zero Volts

Simultaneous Update of Outputs (LDAC Function)

On-Chip Rail-to-Rail Output Buffer Amplifier

The reference for the four DACs is derived either inter-

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

outputs of all DACs may be updated simultaneously using

the software LDAC function or external LDAC pin. The

ADT7316/7317/7318 incorporates a power-on-reset cir-

cuit, which ensures that the DAC output powers-up to

zero volts and it remains there until a valid write takes

place.

wire Serial Interface

16-Lead TSSOP Package

APPLICATIONS

Portable Battery Powered Instruments

Personal Computers

TelecommunicationsSystems

Electronic Test Equipment

Domestic Appliances

The ADT7316/7317/7318’s wide supply voltage range,

low supply current and SPI/I²C-compatible interface,

make it ideal for a variety of applications, including per-

sonal computers, office equipment and domestic appli-

ances.
