GENERAL DESCRIPTION
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
o
C. The ADT7316/17/18 operates from a single
+2.7V to +5.5V supply. The output voltage of the DAC
ranges from 0 V to 2V
REF
, 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
TM
and
DSP interface standards; and a two-wire I
2
C interface. It
features a standby mode that is controlled via the serial
interface.
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.
The ADT7316/7317/7318’s wide supply voltage range,
low supply current and SPI/I
2
C-compatible interface,
make it ideal for a variety of applications, including per-
sonal computers, office equipment and domestic appli-
ances.
